General
The Hengesbach TCF050D pressure transmitter is suitable for measuring pressure in applications with pulsing pressure and the danger of pressure shocks and cavitation e.g. in barrel filling systems. The piezoresistive measurement cells with the ceramic membrane are designed for measurement ranges from 0…1 bar to 0…100bar.
The flush-mounted process connections with G1/2“ / M22x1.5 are equipped with the Hengesbach TCF050D pressure transmitter with diaphragm seals and stainless steel membrane. These are ideal for flush-mounting in small pipe nominal widths. High-temperature versions for constant temperatures of up to 200°C are also available. The stainless steel field housing in IP 67 and IP 69K is resistant to all common cleaning procedures.
All Hengesbach TCF050D series pressure transmitters are equipped with a micro-processor controlled electronics system and an accuracy of ≤ ± 0.4% FS. They are parametrized with a simple and user-friendly operating concept via 2 keys and a multi-color status LED. They are highly suited for applications with basic requirements of functionality and exactness.
