WO81FN(surface installation type with non flag pointer)

WO81PRS(panel installation square type with one flag pointer)

WO81PCT(panel installation round type with two flag pointers)

・Broad line-up of product

・Supporting the air volume scale and the air velocity scale (refer to p.7)

・Readable wide-angle scale (Angle of the pointer-rocation is 270 °)

・It is easy to convert polarity enable by piping connector

・Even when the pressure becomes excessive, the original mechanism avoid damage to moving parts.

・Small hysteresis is realized by the silicone rubber diaphragm.

・The pointer is not fluctated by the original band-linked mechanism.

＊ Because of quality improvement or any reason, some specifications are possibility of changing without notice.

PT connectorThe joint installed tube is push-in type. Use the optional tube (NT4-6, refer to p.88) or the applicable tube (JIS B8381-1).

PR connectorThe joint installed tube is push-in and rotary elbow type.

MT connector(ring joint type)This connector can be connected to the metal tube made from copper, aluminum and so on (O.D. 6, the tolerance ± 0.1).In case of connecting with stainless tube, use MTW connector.When this connector is connected to hard plastic tube (O.D. 6, I.D. 4), remove the brass-made sleeve and use the resinous inner sleeve set (XIN6 × 4, refer to p.88) that is the optional accessory.

MR connectorThis connector is rotary elbow type and can be connected to the metal tube (made from copper and aluminum and so on.).Applicable piping material is the same as MT connector.When this connector is connected to hard plastic tube (O.D. 6, I.D. 4), remove brass-made sleeve and use the resinous inner sleeve set (XIN6 × 4, refer to p.88) that is the optional accessory.

Piping adaptor on back view When you install MT, VR and MR connector (except for MTW connector) on back side port of WO81F type, this adaptor is necessary to avoid interference with connectors and panel. It is also necessary as a spacer to use a locking spanner at this adaptor.

MTW connector(double ring joint type)This connector can be connected to stainless tube (O.D. 6, the tolerance ± 0.1).This connector is made of stainless steel. (SUS316)

VR connectorThese connectors are rotary elbow type and can be connected to vinyl, plastic and rubber tube of I.D.6.
