Mk Series Three Wires Pressure Sensor / Transmitter for Oil Water Gas Air

MK series with a compact structure is easy to install, whose specifications could provide strong compatibility between sensitive components and the measured medium, excellent medium adaptability and long-term stability. It could directly output what you need such as standard voltage, current, or digital signals. Because its PCB is fixed on the mounting bracket, it needs a little installation room and provides strong anti-vibration performance. In terms of its ruggedness, it is widely implemented in various fields.
