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.
