Overview
The WKG-131 is a compact pressure transmitter covering measuring ranges of -0.1~60MPa with accuracy ≤±0.25%FS and a standard 2-wire 4-20mA output (0-5V, 1-5V and 0-10V also available). It runs on a 12-32VDC supply, carries an IP65 protection rating and offers long-term stability of <0.2%/year.
The series operates at working temperatures of -30~80℃ with medium temperatures of -40℃~120℃, and is built in a small form factor that fits tight installations. Housing options include a digital-display head, aviation plug and Hirschmann connector, with process threads M20x1.5, M12x1.5, M14x1.5, G1/4, G1/2, 1/2NPT and 1/4NPT.
Per the selection table, the WKG-131 family includes ceramic (131), diffused-silicon (131), diffused-silicon with digital display (131S), high-temperature (131G), sanitary diaphragm (131MC) and flush-diaphragm (131PM) variants, so the sensing element can be matched to the medium and process.
