INSTRUCTION MANUAL
PERAMIC
WARNING
Before installing the PERAMIC, read the warnings and
advisements on the last page. For personal and system
safety, and for optimum performance, make sure you
thoroughly understand the contents before installing.
DESCRIPTION
The PERAMIC is a solid state, All Stainless, Pressure
transmitter based on a ceramic pressure cell with a very high
burst pressure. The amplifier system is based on a single
Integrated Circuit, which ensures a perfect linearity in the 4-20
mA output. Also the transmitter is fully temperature
compensated. The PERAMIC is made for pressure applications
on liquids, gases and vapors. Zero and Span are internally
adjustable in wide ranges. A local digital indicator is available
(option).
OPERATION PERAMIC
The PERAMIC has no oil filling system, so the process pressure is applied directly to the ceramic pressure
cell. The voltage signal from the ceramic cell is connected directly to the Integrated Circuit that converts this
signal into 4-20 mA. Therefore the PERAMIC has a perfect linearity and is fully temperature compensated.
This means that various process temperatures have no effect on the accuracy of the output signal.

BAROMETRIC REFERENCE:
The PERAMIC is a Relative Transmitter which means that barometric changes will not affect the zero (4 mA).
The venting nipple (3) is placed in the electronic housing and is the barometric reference to atmospheric pressure.
The venting nipple must be kept clean.
