БПВТ-421 Humidity and temperature conversion unit

Order code:

БПВТ-421
ХХ
Temperature measurement channel configuration:

Number:

Available for order.

BPVT-421 is designed to convert the signal from a relative humidity sensor into a standardized 4…20 mA current output 🔁, ensuring stable and noise-immune data transmission to controllers, regulators, or monitoring systems.

The second channel provides:

  • reading and converting the signal from the built-in TSM-50M temperature sensor using a 3-wire connection scheme 🧩, or ​generating a standard 4…20 mA current output proportional to temperature 📈.

🏭 Areas of application

BPVT-421 is used in:

✔ automated control and regulation systems
✔ building microclimate monitoring systems 🏢
wood-drying chambers 🌲🔥 — for measuring temperature and humidity of the environment
✔ measuring systems and data-processing complexes 📊
✔ industrial dispatching and telemetry systems 📡

➡ In wood-drying chambers, BPVT-421 is used together with the IVM-16 indicator, which displays and processes the measured parameters.

Advantages and features

🔌 Standard current output 4…20 mA — reliable signal transmission over long distances
🔄 Two independent channels: humidity + temperature
🔧 Compatible with PLCs, controllers, SCADA systems, and data recorders
🛡 High noise immunity and stable operation under industrial electromagnetic interference
🔁 Suitable for both new and existing automation systems
