These are pressure transmitters designed for semiconductor industry, in which pressures are converted into electric signals and transmitted by the sensing element equipped with an evaporation type semiconductor strain gauge and a built-in electronic circuit. The ZT15 is a pressure transmitter built to accommodate a 1.5 surface mounting interface for semiconductor manufacturing gas distribution and can be applied to the gas panel and the valve manifold boxes, etc. We provide two types of pressure transducers with UC/EP Grade for high-purity gas and GP Grade achieved the cost down of gas piping without impairing the airtightness.
