Product Description


Baoji Hengtong Electronics Co.,ltd was founded in 1994, occupying 80 million of assets,over 7000 squre meters factory,1261 sets of equipment and instruments,with more than 100 workers.

We are specialized in production of pressure, differential pressure, absolute pressure

liquid pressure, temperature transducer and transmitters and the relative smart numeral disply controllers. Our HT series oil-filled sensors with membrane are producted by advanced technology, with features of reliable performance, high precision.

These products have been widely used in automatic measuring and controlling system in field chemical , metallurgy electricity, aero-industry, coal and petroleum exploitation,irrigation and hydrology, and water supply,steam supply ,warm supply of town.Some of the products are used in major national projets, and spoken highly of the relevant state department.

HT30 Piezoresistive Silicon Pressure Sensor


HT30 is piezoresistive Silicon Pressure Sensor, the main element is a diffused silicon with high stability. The measured pressure is transferred from 316L stainless steel diaphragm to sensing element via silicon oil, utilizing the piezoresistance effect of diffused silicon to transfer pressure to voltage signal and fulfills pressure measurement .It is a full-welded Pressure Sensor, Pressure port can be selected by user. It can be used for kinds of field.
