Mass flow controllers RNPA mass flow controller (RNP) is a rotametric flow sensor with continuous measurement of temperature of flowing liquid (water, aqueous solutions) and is intended for thermostating:
- injection moulds
- moulds for shaping rubber by blowing
- extruder heads
- vacuum pumps
- transformer welders
- calibration devices
- and other similar applications.
Float Level Sensors PCPThe float level sensor is intended for signaling the level threshold values of non-crystallizing media.
The principle of operation includes closing (z) or opening (o) contacts of NO contact relays or switching (p) reed switch contacts. The float is equipped with a magnet and moves along the guide tube owing to the force of buoyancy. It closes or opens the contacts of a reed switch. In this way, the limit signal is triggered when the lower or upper level threshold is exceeded. The functionality of a reed switch from opening to closing and vice versa can be switched by changing the position of the float.
