Overview
The WELK Meters explosion-proof pressure transmitter is an intrinsically safe transmitter for hazardous-area pressure measurement, covering ranges of -0.1~60MPa with accuracy ≤±0.25%FS and a 4~20mADC output. It combines an industrial explosion-proof housing with a diffused-silicon sensing core and an on-board digital pressure display.
The transmitter runs on a 12-32VDC supply, carries an IP65 protection rating, operates at working temperatures of -30~70℃ and offers long-term stability of <0.2%/year. It is offered in 0.5-class and 0.25-class accuracy variants.
The same transmitter family is also available with flange-diaphragm and threaded diaphragm-seal process interfaces — see our diaphragm-seal pressure transmitter page, or contact us with your hazardous-area classification and process details for a configuration recommendation.
