Deviceed for the measurement and adjustment of operation between two temperature limits adjustable for the installation in which it is mounted, has a double functionality: 

  -  thermometer, by the indication of the operating temperature within the range 30 ... 90⁰C;

  -  thermostat, by the adjustment in the operation interval between the two limits with an adjustable differential 4 ... 23⁰C. 

The technical features of this device are:

-      Measurement and adjustment range          30…90^oC

-      Adjustable differential                                  4…23^oC

-      Indication error                                              +- 2^oC

-      Protection degree:                                         IP 54

-      Ambient temperature:                                   -30....60°C

-      Working agent                                               Freon R 600A

-      Working media                                               non corrosive fluids

       The pressure switch or the electrical switch acting by pressure is a device being a part of the elements automation class. It works on the forces balance principle between the force as a pressure action on the effective surface of the elastic element from the sensible element sub-assembly and the force given by one domain spring and the imbalance of these forces according to the pressure raise or decrease  makes possible by a rod, the change of the  pressure switch electrical contact position.

Technical features:

-          pressure adjusting interval: 1…10 bar;

-          the max. pressure: 12 bar;

-          fix or adjustable differential: 1…3 bar;

-          connecting error: +-0,2 bar;

-          micro-switch with separate contacts or with common point, NI and ND, with electrical tension 220 Vc.a.; 50 Hz; 10A; cos F 0,8;

-          protection degree: IP 54;

-          ambient temperature: -25^°C…+60^°C;

-          working media: non-corrosive fluids
