Variohm EuroSensor launches Prignitz pressure sensor range

26 January 2011

Variohm EuroSensor has introduced a range of pressure sensing, transmitting and display products following a new exclusive distribution agreement with the German manufacturer Prignitz Mikrosystemtechnik GmbH. The Prignitz range will broaden Variohm's application capability with flush diaphragm pressure sensors for food and biomedical/pharmaceutical uses, as well as differential low and high pressure switches with integral displays for the processing, water treatment and HVAC industries.

The Prignitz range is compliant with ISO 9001:2000 standards and many pressure sensing products have ATEX approvals. The Company also takes a flexible approach with custom manufacture available throughout its product range.

The  SIT  pressure transducer, based on the latest thin film silicon measurement technologies, is available in two main versions. The DM variant is aimed at food and pharmaceutical pressure measurement up to 40bar and is designed in accordance with European Hygienic Engineering & Design Group (EHEDG) guidelines, whilst the PTLM variant is used for industrial applications of up to 4,000bar. Both versions have several measurement range options and have rugged stainless steel construction with IP65 protection ratings as standard.

Flush diaphragm options are available throughout to prevent material build up on the diaphragm and facilitate easy cleaning. In particular the DM version has an extremely smooth RA value surface finish for the pressure contacting elements. The SIT range can be supplied for voltage or current output and features a PC programming capability for zero-point, offset, range and many other characteristics in addition to a straightforward zero correction feature using a simple external magnet.

The DPTM range is a compact differential pressure transducer for liquid and gas measurement up to static pressures of 1000 bar. Aimed at pneumatics, process engineering and HVAC, the IP66 rated unit is supplied in 0-10Vdc and 4-20mA versions both with and without a four-character display. The DPTS-20 is similar in construction and is used for air and non aggressive gas pressure measurement offering a switching function that is suited to HVAC applications such supervision systems for air filtration and ventilators.

Other Prignitz pressure measurement products now available from Variohm include the extremely compact SPT-SK pressure transducer for liquid and gas pressures to 40bar. The thin film silicone technology sensor offers an excellent price-performance ratio and is especially suited to building HVAC and OEMs for domestic water and air conditioning monitoring. Also available is the new rugged DPTP differential transducer for panel or DIN rail mounting. Measuring just 85mm x 48mm x 34mm deep and with removable connectors for ease of installation, the ABS moulded plastic sensor uses patented silicon-glass technology and will suit low pressure applications in building automation, ventilation and air conditioning up to 0-25Pa to 0-6kPa differential pressure. The DPTP range also has traceable calibration to Deutscher Kalibrierdienst (DKD) standards.
