Features: Adopted of Epoxy resin sealing structure so it is shake proof and 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 resistan ce ALS-XQWD-1MF, 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 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.
