Features:
- Adopted of Epoxy resin sealing structureso it is shake proofand temperature-resistant, suitable for installation and use in harsh site environment.
- It is installed in the junction box of thermal resistance and thermocouple on site to directly output 4-20ma and 0-10ma signals, which not only saves costs, but also improves the anti-interference ability in the long distance transmission of signals.
- High precision, low power consumption, wide range of ambient temperature, stable and reliable work.
- Adjustable range , and it has more linear function, thermocouple temperature transmitter with cold end automatic compensation function.
- It can be used in a wide range of applications. It can not only form a bulk field installation structure with thermocouple and thermal resistance, but also be installed into the testing equipment as a functional module.
Specification:
Input: thermal resistance Pt100, Cu50, Cu100(two-wire/three-wire/four-wire)
Thermocouple K, E, S, B, T, J, N(two-wire)
Intelligent input signal and range can be set by PC or hand controller.
Output: the output of 4~20mA dc signal within the range can be linear with the output resistance signal of the thermal resistance thermometer and the input temperature signal of the thermal resistance thermometer; Linear with the input millivolt signal of the thermocouple or with the input temperature signal of the thermocouple thermometer.
Basic error:0.2%,0.5%
Transmission mode: two-wire system/three-wire system/four-wire system
The working power supply voltage of the transmitter :24V.
Load: the ultimate load resistance is calculated according to the following formula
RL(Max)=50X(vmm-12), that is, the load resistance at 24V can also be selected in the range of 0-6000) rated load 250 days.
Note: the adjustable range transmitter, the zero point and full degree need to be adjusted repeatedly when changing the range: the electric couple transmitter must be preheated for 30 minutes before debugging.
