WT Sensor Air Water Oil 4-20mA Piezoresistive Silicon Pressure Transmitter PCM303 4bar gauge 4-20mA G1/2 DIN43650
Main Features
High Accuracy;±0.075%F.S
Good stability;
2-wire type;
Solid components, plug-in printed circuit boards;
Small size, light weight, strong and anti-vibration;
The range and zero point are continuously adjustable externally; smart models need to be equipped with Hart handheld programmer/software or adjustment in the shell
The positive migration can reach 500%, the negative migration can reach 600%; the intelligent turndown ratio is 100:1
Adjustable damping;
Good one-way overload protection characteristics;
No mechanical moving parts, less maintenance work;
Unified structure of the whole series; strong interchangeability of parts and components;
Diaphragm material in contact with the medium can be selected (316L, tantalum, Hastelloy C, Monel and other corrosion-resistant materials)
Application
Widely used in pharmaceutical, medical equipment, oil, gas, chemical, urban construction power, metallurgy, textile, aerospace, scientific research, leak detection, automation equipment and other fields.
