HQ-308 (formerly 2088) diffused silicon pressure sensor features: reverse polarity and current limiting protection; laser trimming and temperature compensation; zero point and range can be adjusted on-site; wide range and corrosion resistance, suitable for various media; strong overload and anti-interference capabilities, and stable performance.
HQ308 Diffused Silicon Pressure Transmitter
HQ308 Diffused Silicon Pressure Transmitter Product Overview
The HQ308 series pressure transmitters are characterized by
reliable operation, stable performance, convenient installation and
use, small size, light weight, and high performance-price ratio.
They can be widely used in various positive and negative pressure
measurements.
The HQ308 series pressure transmitters use imported diffused silicon or ceramic cores as pressure sensing elements. The sensor signal is converted into a unified 0~10mA or 4~20mA output signal by a high-performance electronic amplifier. It can replace traditional remote pressure gauges, Hall elements, and differential transmitters, and has the performance characteristics of DDZ-I and DDZ-II type transmitters. It can be used with various types of moving-coil indicators, digital pressure gauges, and electronic potentiometers, as well as various automatic control systems or computer systems. It is widely used in power, petrochemical, machinery, metallurgy, and other industries, as well as various energy metering fields.
