Our Products
Our product range contains a wide range of Melt Pressure Transmitters and TPSA Pressure Transmitter
The IMPACT series of Gefran, are pressure transmitters, without transmission fluid, for using in High temperature environment (350C). Medium pressure is transferred directly to the sensitive silicon element via a thick diaphragm. Strain is transduced by a micro-worked silicon structure (MEMS). The operating principle is piezoresistive. IMPACT is Gefrans exclusive series of high-temperature pressure sensors that use the piezoresistive principle. The main characteristic of IMPACT sensors is that they do not contain any transmission fluid. The sensitive element, directly positioned behind the contact membrane, is realised in silicon through microprocessing techniques. The micro structure includes the measurement membrane and piezoresistors. The minimum deflection required by the sensitive element makes it possible to use very robust mechanics. The process contact membrane can be up to 15 times thicker than the membrane used in traditional Melt sensors
Series TPSA transmitters are based on bonded strain gauge on stainless steel technology.
An innovative mechanical structure makes the transducer completely insensitive to tightening.
This transducer is suitable for allapplications where along with robustness an elevated accuracy is required.
