PT... series pressure transmitters are widely used in HVAC, medical and sanitary and industrial fields. They are suitable for measuring air, water, ammonia water, steam and other medium pressures, as well as corrosive media that are compatible with 316 stainless steel. The products adopt imported diffusion silicon type sensors, amplify and linearize the signals, and output DC 4mA~20mA signals proportionally according to a certain pressure measurement range.
The PT series pressure transmitters are designed for measuring the pressure of air, water, steam and other media, including corrosive fluids compatible with 316 stainless steel. They are widely used in HVAC, medical, pharmaceutical and various industrial fields. The devices feature an imported diffusion silicon sensor, signal amplification and linearization, providing a proportional 4‑20 mA DC output.
The manual provides technical specifications, model‑specific measurement ranges, wiring diagrams, and installation guidelines. It details power requirements, accuracy, temperature range, material construction, and recommended connection interfaces (7/16" 20UNF or M20×1.5). Proper wiring with shielded two‑core PVC cable and safety precautions are also described. This manual is written in Chinese.

It provides a 4 – 20 mA current output signal.
The transmitters operate from a 24 V DC supply (or 15‑36 V DC under certain load conditions).
Standard connection interfaces are 7/16" 20UNF or M20×1.5 threads.
They are used in HVAC, medical and pharmaceutical equipment, industrial processes, refrigeration, hydraulic and flow control systems, and air‑compressor control.
