Sensors and Pressure/Temperature Switches
ASCO pressure sensors provide accurate measuring and linear electrical output signals for many process fluids. The MEMs based sensor and one-piece pressure cavity provides stable output measurements from 0 to 10,000 psi and supplies high sensitivity, low drift and highly repeatable signaling.
Electrical options include flying leads, pins, spade terminals, or explosion-proof or intrinsically safe versions. Mechanical options include panel mounting, 316ss pressure vessel or inconel with process connections of 1/8-1/2 inch NPT, and other specialty threading. Output signal options include 4-20m Amp or 1-5 Volt.
