Duchin Instrument launches the DZWB Series Temperature Transmitters to complete industrial temperature signal conversion solutions. The series linearly converts raw measurement signals from thermocouples and thermal resistors into standard industrial signals, suitable for temperature measurement and control in diverse industrial process scenarios.
A temperature transmitter converts the non-linear millivolt signals and resistance signals output by temperature sensors into linear standard signals. The prevailing output specifications include 4~20mA DC and 1~5V DC, facilitating data acquisition and processing by back-end devices such as PLCs and display instruments.
Diversified Product Categories for Multiple Mounting Configurations
The DZWB Series falls into two structural categories:
Integrated Temperature Transmitter Modules (1=2 in model code): The module is directly installed inside the terminal box of thermocouples or thermal resistors to output standard signals on site, adopting a 2-wire wiring scheme in most applications.
DIN Rail / Cabinet-mounted Temperature Transmitters (1=3 in model code): Independently mounted and separable from temperature sensors, designed for centralized installation inside control cabinets.
Products are available in isolated and non-isolated signal processing versions. Comprehensive thermocouple type coverage includes K, N, E, J, T, S, R, B, C and D. Supported thermal resistors cover Pt100, Pt1000, Cu50 and Cu100. Universal input models are also offered. Available outputs include 4~20mA, 0~5V, 1~5V. Extended options include RS485 communication and wireless transmission.
