Product overview
ABSD-131WD temperature transmitter ABSD series temperature instrument in the field installation type
temperature transmission unit. The two-wire transmission method (two wires as power input, signal output
common transmission line) is used. PT100 RTD signal into an electrical signal or the measured temperature into a
linear 4-20mA output signal, the transmitter can be installed in the junction box of the RTD and form an integrated
structure. It can be widely used in metallurgy, petrochemical industry, electric power, light industry, textile, food,
national defense and scientific research and other industrial sectors.
Product features
1. The epoxy resin sealing structure is adopted, so it is shock-resistant and temperature-resistant, and is
suitable for installation and use in harsh field environments.
2. It is installed in the junction box of the thermal resistance on site and directly outputs 4-20mA, which not
only saves the cost of expensive compensation lines, but also improves the anti-interference ability during
long-distance signal transmission.
3. High precision, low power consumption, wide range of ambient temperature, stable and reliable work.
4. The range is adjustable and has the function of linearization correction. Wide range of applications, it can
form an integrated on-site installation structure with the thermal resistance, or can be installed into the testing
equipment as a functional module.
Main technical parameters
Input signal
RTD Pt100
Output signal
The output signal of 4-20mA DC within the range can be linear with the output resistance signal of RTD
thermometer, and can be linear with the input temperature signal of RTD thermometer.
Technical parameters
Basic error:±0.5%FS
Transmission mode:Two-wire system
Working voltage: Minimum 11V, maximum 36V, rated working voltage 24V
Load: The ultimate load resistance is calculated according to the following formula
RL (max)=50×(Vmm-12)
That is, the load resistance at 24V can be used in the range of 0-600Ω, and the rated load is 250Ω.
Note: Range adjustable transmitter, the zero point and full scale need to be adjusted repeatedly when
changing the range.
