Equipment and systems covered by this certificate are as follows

Pressure transmitters PC-28, PCE-28 are designed to measure positive gauge pressure, vacuum pressure and absolute pressure of gases, vapors and liquids.The transmitters PC-28P, PCE-28P are designed to measure of level of liquid.Differential pressure transmitters PR-28, PRE-28 are designed to measure liquid levels in closed tanks and to measure differential pressure across constructions. The electronic part is identical in all versions.The active sensing element is a silicon diaphragm with in-diffused piezoresistors located in a sensing module.The electronic part amplifies and standardizes the signal from measuring bridge to the output signal 4 to 20 mA.The electronic circuitry except of filter board is encapsulated in a stainless steel enclosure.The external circuit connection facility differs according to the model as follows:

  •  PD (angular connector produced by Hirschmann)
  •  PZ (terminal box with cable gland PG-11)
  •  PK (permanently connected cable). The letters xx indicate type of process connector, yy indicate the type of electric connector.

The transmitters intended for use as group II equipment are allowed to be installed into the partition between the hazardous areas zone 0 and zone 1. 
Technical parameters: Ui = 28 V DC; Ii = 0.1 A; (for linear power supply characteristic), Ii = 0,08 A (for rectangular or trapezial power supply characteristic).  Pi = …see the table in attachment , L= 0.9 mH; Ci = 40 nF

Ambient temperature:   Ta …see the attachement
