The document introduces the features and characteristics of the PROTRAN series PR3400 immersion depth transmitters, including high stability and repeatability, all stainless steel housing, resistance to high voltage shocks, adjustable zero and full scale, etc. The transmitters are designed for accurate measurement of depth and liquid level, and can be connected at the surface or for remote amplification testing. Different models are suitable for different applications, such as sludge/mining slurry level, storage tanks, liquid level, drilling fluid level, etc.
The PROTRAN PR3400 series is a stainless‑steel depth and level transmitter designed for accurate measurement of water depth or liquid level. It offers a standard 4‑20 mA two‑wire output and adjustable zero and span settings.
Key features include a measurement range of 0‑2.5 m to 0‑500 m, IP69 protection, operating temperature from –20 °C to +85 °C, and robust electrical characteristics such as DC13‑36 V power supply and 100 MΩ insulation resistance. This manual is written in Chinese.
