3 Product OverviewIncus is an ultrasonic gas leak detector which detects the airborne ultrasound generatedfrom pressurised gas leaks.

Airborne ultrasound is generated when gas moves from a high pressure area to a lowpressure area with a ratio ≥ 1.8: 1 upstream to downstream pressure. The intensity ofairborne ultrasound generated by a leak is due to a number of factors, including but notlimited to, gas pressure, leak size and gas temperature. The use of Incus as a leak detectoris only recommended for pipelines running at pressures > 2 bar.

Incus uses four individual piezo-ceramic sensing heads, mounted using Emerson’s™

patent-pending floating-crystal design. The sensor design makes the sensing headsvirtually indestructible and totally immune to temperature, moisture, and othercontaminants found in hazardous industry. Incus has a wide dynamic range whichfacilitates use in a variety of applications from laboratories to turbine houses. The multi-stage amplifier ensures a linear output across the entire detector range without drop-offat each end of range.

Incus is not designed to detect specific gas types or to measure percentage LEL or ppmconcentration level, but instead responds instantaneously to a wide range of leak sizeswhile being unaffected by even the most extreme weather conditions. Incus is rated toIP66 / IP67 to withstand harsh environments and continues to work during temporaryimmersion.

Incus uses a continuous electronic background monitoring test feature to ensurecomplete functionality. This testing is invisible to the user and does not interrupt thenormal detection operation of the sensor. Incus also has an optional heating facility whichenables the internal electronics to be kept within normal parameters with externaltemperatures as low as -67 °F (-55 °C). (Even lower temperature operation is possible,although cold startup cannot be guaranteed). The heater uses a proportional-controlscheme, meaning the unit can be kept within an optimal operating temperature rangewhile minimising the additional current draw from the incoming +24 V supply.

Incus has complete customer flexibility. The current-loop output can be factory configuredas source or sink, and the scale-factor can be configured to mimic other vendor’s detectoroutputs. Also provided is a multi-drop RS485 diagnostic port using an Emerson-proprietary protocol. Incus also features infrared communication, using the sameproprietary protocol, which allows parameter interrogation and setting ability from up to8M range using a proprietary USB-IR interface adapter. This allows non-contact setup ofparameters after installation.

Incus with software version 2.6 onwards has HART® communication enabled by default.

4 Product Interfaces

4.1 Process interface

4.1.1 Sensor input channelsThe Incus uses four floating piezo ceramic heads to detect a pressurised gas leak.Information about the sensor channels can be found in the Incus Reference Manual.

4.2 Host interface

4.2.1 Analog output channel (current loop)The Incus is wired as a three wire sensor using the terminals marked 0 V, +24 V, and mAinside the terminal compartment. Detailed connection details can be found in the IncusReference Manual. The current-loop output is factory configured as either source or sinkmode (default is source). If the Incus is configured for source mode the current loop isconnected between mA (+) and 0 V (-) terminals. If using a sink mode Incus, the currentloop is connected between +24 V (+) and mA (-).

This current-loop output is configured to be proportional to the primary variable (dB SPL);the specific 4-20 mA signal level and scale-factor details can be found in the IncusReference Manual. The scale factor varies according to the operating mode selected. Themanual also describes the device malfunction indications that are available, signalled byspecific DC current levels below 4 mA viz. 2 mA, 1 mA, and 0 mA. See Operation withWirelessHART® Adapters for implications of using external WirelessHART® adapters withthis signalling scheme.

HART communication is supported on this loop. In order for HART to operate successfully,the loop should be terminated with a resistor in the range of 100 – 500 ohms, generally inthe control room.

NoteThe Incus current-loop output operates in Active mode, meaning the power to the loop isprovided by the sensor itself.

4.2.2 Relay outputsThe Incus has configurable relay outputs used to indicate a device fault and alarmcondition. These relay configurations are not accessible through the HART® interface.Refer to the Incus Reference Manual for more information.

4.3 Local interfaces, jumpers, and switches

4.3.1 Local controls and displaysThe Incus has a seven segment display to relay information back to the user. The displayedinformation cannot be controlled by the HART® interface. More information is containedin the Incus Reference Manual.

11 Performance

11.1 Sampling ratesPlease refer to the Incus Reference Manual for details of the measurement process.

11.2 Power-upUpon power-up, a brief diagnostic check will run to ensure detector functionality. Thischeck will last for no more than 10 seconds. Once the check is completed, Incus will gointo normal operation using the factory/customer defaults specified at time of order orsignal any faults that may be present. No response to any HART® command is guaranteedduring the power-up phase.

More information on the power-up sequence is available in the Incus Reference Manual.

11.3 ResetCommand 42 (Device reset) is not supported.

11.4 Self-testThe Incus does not support command 41 (Self-test). A self-test is continuously performedduring the normal measurement cycle. Any errors or faults can be determined usingcommand 48 (Read additional device status). More information about the self-test can befound in the Incus Reference Manual.

C Operation with WirelessHART®

Adapters

C.1 Two-wire (loop powered) WirelessHART®

adaptersOwing to the use of sub 4 mA signalling levels for indication of fault conditions, thestandard operating modes of the Incus are not suitable for use with loop-poweredWirelessHART adapters, e.g., the Emerson™ THUM.

These wireless adapters generally have a minimum operating current level of 3.5 mA;below this level, they are not guaranteed to have sufficient power to remain connected tothe wireless network. Within the Incus, special operating modes are provided in which thelow loop current signalling modes are inhibited. This may facilitate operation with thistype of wireless adapter. Alternatively, for Device Revision 2 and greater, loop current maybe parked at 3.5 mA, (via HART command 6) for wireless only operation. Contact Emersonfor further information.

C.2 Three-wire Ex d/Explosion Proof certifiedWirelessHART® adaptersThe Incus has been verified for operation with suitably certified WirelessHART adapters;these adapters can be powered from a local DC source, e.g., the Mactek Bullet(1). A typicalwiring diagram is shown in Figure C-1 below. The loop termination resistor shown can bemounted inside the Incus terminal enclosure, using a two-way splice block. Alternatively,the resistor could be part of the Input card in the control room. The Bullet also has thefacility to switch its own termination resistor into the circuit, under control from a localEmerson™ 475 handheld field terminal, AMS configuration software, or a device runningthe Pactware FDT software and Bullet DTM.

(1) May require a Bullet firmware update.
