The Argus pressure, differential pressure, temperature, level and flow switches are designed for use in environments where explosive gases and extremes of both high and low ambient temperature can be present (e.g. Gas fields, Oil rigs and Chemical plants etc.) They have been ATEX certified for CAT 1 CE Ex II1G Exia IIC T6,T5 & T4 and CAT 2 CE Ex II2G Exd IIC T6,T5 & T4.

These switches are manufactured from either PPS (engineering polymer) or high quality investment cast 316 stainless steel both offer a robust construction and protection to IP67 for use within heavily polluted industrial and marine environments. These instruments can be adjusted with the power on and the switch in operation. Declaration available for SIL2 - IEC61508 proven reliability.

ARGUS ATEX Exd, Exia & INDUSTRIAL SWITCHES

INTRODUCTION

The design features a simple form of calibration adjustment against a scale block.This allows users to either order units with a specific setting, or stock a mid range setting and then adjust to suit the application. This can be set safely with the switch supply live.

On removal of the adjustment cover the adjusting screw can be turned with the small Tommy bar supplied. The setting is read from the centre of the red indicating ring against the internal scale plate. Rotation to the left will increase the set point and to the right decrease the set point. The adjustment mechanism incorporates a friction device to ensure set point will not change under vibration conditions.

CALIBRATION

ccWe have extensive experience gained over 50 years of supplying most sectors of industry and believe these cus-tom asssemblies can assist cost saving. A recent example of this was an approach made to us by a leading com-pany from the fire protection sector. They had previously been mounting 6 switches on a bulkhead and individually wiring each switch back to an Exe enclosure via armoured cable and certified cable glands.

Our solution, which can be seen above, was to supply a stainless steel EExe junction box fitted with 6 x Exd pressure switches. We incorporated manifold valves and supplied a complete wired assembly. This was bolted to a bulkhead and the process connections attached. The concept saved them considerable time as the pressure switches did not require to be individually mounted and wired.

In addition, a single order was placed, when normally separate orders for switches, junction boxes and manifold valves would have been required. Our customer and their inspection authority were so impressed with the initial system that we received an order for 80 sets.

Our experienced engineers work closely with our customers enabling us to maintain our position as a leader in the control and instrumentation field. This close relationship has resulted in switch ranges such as the Argus as well as an expanding range of instrumentation products. We are in a position to offer a full range of switches, indicators and transmitters for industrial or hazardous area applications no matter how arduous.

ARGUS SWITCH AND JUNCTION

BOX ASSEMBLY

The Argus range of pressure, temperature, differential pressure, level and flow switches manufactured by Pyropress are now available with EExd and EExia ATEX certification. There is also an industrial version enabling one range of switches to be used for all applications.

Pyropress are offering switch, transmitter and junction box assemblies suited for hazardous area and industrial ap-plications. They are custom designed and are delivered fully assembled and wired. We can also incorporate gauges and manifold valves and additional terminals for other instrumentation.

The Argus range is available with a non corrosive robust PPS (engineering polymer) case or 316 stainless steel, both being certified to IP67 standards of protection. The can be used for high and low ambient temperature between-50 and +128°C. Full details of the complete range can be found in our control sensors booklet or on our website www.pyropress.com.

In keeping with our long standing customer oriented philosophy, the entire organisation constantly strives to improve the effectiveness of our service. Computerised order processing and communication systems plus large stocks of standard and special parts, and a highly skilled workforce ensure that your orders receive prompt attention from initial quotation through to shipment.

A full procurement and project management services ensures a complete turnkey package of equipment and ser-vices which can be sought from a single source rather than incurring costs and inconvenience of multiple suppliers.

ARGUS LEVEL

Switching is effected in this unit through transforming by means of an eccentric cam at fulcrum, the vertical motion of the float with level change to the considerably reduced movement of a horizontal switch plunger which is arranged to operate a SPDT/SPCO microswitch. Isolation of the switch mechanism from the liquid monitored is effectively maintained by the use of a ‘O’ ring seal on the horizontal switch plunger.

This type of level switch can therefore be used on tanks under pressure or vacuum, being suitable for pressures up to 3.5 Bar and liquid temperatures up to 100˚C.

The device can be mounted through a 27mm hole drilled in the side tank with nitrile bonded seal and back nut provided. Alternatively it can be fitted in a suitable tank cover plate of sufficient dimension to allow insertion of the switch complete with float.

TYPE L520 VERTICAL LEVEL SWITCHThis design is suitable for mounting through a tank top or cover and utilises a free float principle. The float is allowed to travel unrestricted up or down the rod in response to level change between the limits set by the upper and lower adjustable rod collars which are fixed in position at preselected points.

Both types L520 mode A (for high or low alarms) and type L520 B (with a latching mechanism suitable for pump control) can be installed in non-pressurised tanks and sumps with liquid temperatures up to 100˚C. They can be fitted with a cover plate or flange to ease installation. The float rod can be supplied between 500mm and 2000mm to suit application, the required length must be stated upon ordering. Each float switch is tested and adjusted individually to suit float and & rod fitted. A back nut and nitrile bonded seal are provided to aid installation.

ARGUS FLOW

As will be apparent from the illustrations the complete flow switch comprising orifice plate, differential pressure sensitive element and switching mechanism are combined in a single compact assembly which enables easy installation between pipe flanges, models being available for pipe sizes 15 to 250mm diameter.

Each instrument can be provided with one of seven standard orifice ratios which enables a wide range of flow rates to be accomodated.

The accuracy of such calibration will be affected by many external factors such as fluid temperature change, pipe layout etc, but experience has shown this to be within +/-5% for a given set of conditions.

These sensors incorporate a spring loaded pressure sensitive flexible diaphragm, which when deflected by pressure drop across the orifice plate, actuates directly by push rod a snap action S.P.D.T. microswitch at the flow setting selected on the adjustment scale.

Flange casting: Gunmetal, standard, stainless steel or Tufnol Expoxide (Exd & industrial only) material can be provided. Orifice plate: 316 stainless steel or acetal. Diaphragm: Nitrile (standard) or Viton.

Maximum working pressure : 12 bar. Maximum working temperature : 100˚C

For part number breakdown please refer to our sales office

Each instrument is tested before despatch and switch set point marked on adjustment scale. If specially ordered this scale can be calibrated to indicate the adjustable range of flow rate in litres, hour or other units of measurement as required.

FLOW

When using fluids other than fresh water these values will of course alter. It should also be noted that the head loss values are those occurring immediately across the orifice and that up to 50% of this head loss can be recovered by providing at least ten diameters of straight plain pipe either side of flow switch.
