Product Introduction
Small Differential Pressure Transmitter CS-PT500D Product Description
The CS-PT500D series differential pressure transmitter is a high-reliability, high-stability, high-precision, large-range differential pressure transmitter designed after years of intensive research. It is widely used for differential pressure detection of liquids and gases.
The product adopts a 1Cr18Ni9Ti stainless steel or brass housing structure, imported oil-filled differential pressure core, and specially designed amplification and conversion circuit, with features of high voltage, high current, strong magnetic field resistance, and non-polarity wiring.
It has passed intrinsic safety explosion-proof, isolated explosion-proof certification, and CE certification.
It can be designed in programmable mode according to user needs for easy on-site adjustment of zero point and range.
