WB integrated temperature transmitter is a contact site with instruments to measure temperature, usually their corresponding secondary instrument or computer acquisition measurement system supporting the use, can accurately measure the temperature of the production process in a variety of media work or objects (using the range of -200 ℃ ~ 1600 ℃).
WB integrated temperature transmitter is waterproof or explosion-proof junction box assembly temperature sensor mounted transmitter amplification module, and the sensor is connected to form an integrated, output standard 4 ~ 20mA DC (two-wire) .JWB explosion Integration temperature transmitters, while meeting the flameproof d II BT4 and intrinsically safe explosion-proof performance iaII CT5 of (intrinsically safe barrier must be fitted).
This series of products GB reference to the relevant standards and regulations related content JJG issued by the State, taking and related documents in accordance with IEC standards, and with reference to the advantages of similar products at home and abroad to optimize the design of the entire product more reliable and accurate, ideal for a variety environmental site temperature measurement.

1, the basic structure: Sensor + (connecting device + junction box + protective tube) + transmitter module
2, the length of representation: L = total length * protection tube insertion length (unit: mm, sealing surface following is inserted length)
3, to determine the length of the cold end: Because determining the overall length of the protective tube and inserted length, will determine the length of the protective tube of non-insertion portion, namely the length of the cold end of the cold end length standard 150mm; the temperature below 125 ℃. measurement, see the impact of temperature on the cold side of the situation can be appropriately extended, such as 250mm or 300mm.
4, the length of the cold end uses:
a, transmission module operating temperature of -10 ~ 75 ℃, through the length of the cold end of the temperature field to conduction and radiation to reduce the temperature between the junction box to protect the circuit transmission module.
b, if you must have a thermocouple sensor cold end length.
c, to protect the terminals and cables.
