Pressure sensors

Description
Technical data
This electronic pressure switch has a 4-digit, digital display, two
switching outputs and an analog output signal for switching point Order number 234-10330-4
and hysteresis. Both can be adjusted via push buttons. The water- Function principle analogue/digital pressure switch
proofed housing is pivotable up to 290° for optimal readability of Lubricant oil, fluid grease and grease up to NLGI 2
