Pressure Transducer - TTF-1

Brand: WIKA Alexander Wiegand SE & Co. KG

The cylindrical measuring cell of the pressure transducer model TTF-1, as standard, is made from robust stainless steel and as a result exhibits high overpressure and burst pressure safety. For specific applications suitable materials are optionally available.
