Keller Series 7LHP Piezoresistive OEM High Pressure Transducer

Quick Overview

The 7LHP Series are high pressure transducer with a robust stainless steel housing for optimum long-term stability for a wide range of OEM applications. The transducers includes a robust and corrosion-resistant front-flush diaphragm welded with no gaps and an insulated piezoresistive pressure sensor encapsulated in an oil-filled metal housing with O-ring and support ring. Transducers are available with Stainless Steel, Inconel and Titanium for operating pressures up to 2,000 Bar and temperature for up to 180°C. Low power consumption: 1mA (Max 3mA) and typical output signal range of 160mV/mA. Transducers supplied with calibration sheet.
