HQ308 Diffusion Silicon Pressure Transmitter Product Overview
The HQ308 series pressure transmitter has the characteristics of reliable operation, stable performance, easy installation and use, small size, light weight, and high cost-effectiveness, and can be widely used in various positive and negative pressure measurements.
The HQ308 series pressure transmitter uses imported diffused silicon or ceramic core as the pressure detection element, and the sensor signal is converted into a unified output signal of 0-10mA or 4-20mA through a high-performance electronic amplifier. It can replace traditional remote pressure gauges, Hall elements, and differential transmitters, and has the performance of DDZ-I and DDZ-II transmitters. It can be used in conjunction with various types of dynamic coil indicators, digital pressure gauges, electronic potentiometers, as well as with various automatic adjustment systems or computer systems. Widely used in industries such as electricity, petrochemicals, machinery, metallurgy, and various energy measurement fields
