Dwyer Series 7116 Spirahelicl Pressure Indicating Transmitter

4-20mA Signal, 2-wire operation. Dial Gauge Indication.

The Series 7116 Spirahelic® Indicating Pressure Transmitter provides both an ASME Grade 2A accuracy analog pressure gage for precise local indication and a versatile 2, 3 or 4 wire, 4-20 mA output signal for remote monitoring and control. Unique triple wound Bourdon tube movement drives pointer directly with no gears, cams or linkages which can wear and fail early. Sensitive silicon sensor is permanently bonded to small diameter Inconel® X-750 tubing. Stainless steel pressure connection block allows a choice of horizontal or vertical piping. Electrical connections, zero and span controls are located on rear.
