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
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.
DIMENSIONS
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.

- Page 1 (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.
- Page 2 12 mA at atmospheric pressure. If not the above sequence should repeated. INSTALLATION When mounting the PERAMIC, use the same principles as used for manometers (gauge). We recommend using shut-off valves and water trap pipes according to BS/DIN standards, especially on steam applications and those applications where the process temperature will be higher than 212°F.
- Page 3 The PERAMIC is certified for applications in hazardous areas. Certification: II 1G Ex ia IIC T4 Ga (intrinsically safe). When the PERAMIC is used in such areas, use a certified power supply, from 13 - 26.5 Vdc. Installation of this device has to be carried out by a certified and qualified mechanic or a certified and qualified installer.
- Page 4 When the PERAMIC is used as a level transmitter, be aware of the place where the transmitter is mounted. Here are some advises: DO NOT mount a level transmitter in or near filling or discharging pipes.
- Page 5 EU-DECLARATION OF CONFORMITY Klay Instruments B.V. Nijverheidsweg 5, 7991 CZ Dwingeloo, The Netherlands Certify that the equipment intended for use in potentially explosive atmospheres, only new products, indicated here after: Electronic Pressure- and Level Transmitters Series 8000-SAN, Series 8000, Series CER-8000 Hydrobar-Cable, Hydrobar-EXTD, Hydrobar-FR Are in accordance with: - Directive 2014/34/EU (Equipment and protective systems intended for use in potentially explosive atmospheres)
