ZSE40A(F) Series 2 Colour Display High Precision Digital Pressure Switch

Share to:
1. ZSE40A(F)/ISE40A series is a 2-color display high-precision digital pressure switch offering compatibility with both compressed air and non-corrosive liquids. 
2. Z/ISE40 is for vacuum, positive and compound pressure. Can copy to up to 10 switches simultaneously, simpler setting and easier operation. The 4-digit display allows easy reading of displayed values. 
3. Z/ISE40 is UL/CSA, CE, and RoHS compliant.

*1) If applied pressure fluctuates near the set value, set the hysteresis above the fluctuation range to prevent chattering. 

*2) When analog voltage output is selected, analog current output cannot be used together. 

*3) When analog current output is selected, analog voltage output cannot be used together. 

*4) UL temperature rating: The maximum ambient temperature is 50.
