Pressure Sensors

WIKA pressure sensors and transmitters with 4-20 mA or voltage output: A-10 for general industrial duty, S-20 for demanding service to 1,600 bar, R-1 for heating and refrigeration, IS-3 intrinsically safe with ATEX and IECEx approval for hazardous areas, HP-2 for ultra-high pressure to 15,000 bar, S-11 with a flush diaphragm for viscous and particle-laden media, MG-1 for oxygen and medical pipeline services, and the DSS series with a diaphragm seal in hygienic clamp, DIN 11851 and SS 1145 forms and in threaded and flanged forms for chemical and process duty. The A2G air2guide range covers differential pressure and air flow in HVAC ducts up to 12,000 Pa, with Modbus RTU on several models. Specify measuring range, output signal and supply voltage, process connection, wetted material (316L, or Hastelloy C276 where the medium demands it), ingress protection, and the area classification if the point sits in a hazardous zone.
