是DDZ-S系列仪表中的现场安装式温度变送单元。 Temperature transmitter with thermocouple or thermal resistance is a field-installed temperature transmission unit in DDZ-S series instruments. Temperature transmitter with thermocouple or thermal resistance integrates thermocouple or thermal resistance with the transmitter as a whole, directly measures the temperature of liquid, steam and gaseous medium in the range of -200 ～ 1600 ℃ in various industrial processes. It is converted into a 4-20mA unified output signal that is proportional to the electrical signal of the thermocouple and the thermal resistance, and sent to the display, recording and adjusting instrument or computer. 作为新一代的温度变送器， 它可广泛用于冶金、石油、化工、电力、轻工、纺织、食品、国防及科研等各部门。 As a new generation of temperature transmitters, temperature transmitters with thermocouples or thermal resistances can be widely used in metallurgy, petroleum, chemical, power, light industry, textile, food, national defense and scientific research departments. zzyfwh.com
The transmitter components are miniaturized and can be installed in the junction box of a thermocouple thermal resistance to become an integrated temperature transmitter.
，又提高了信号长距离传送过程中的抗干扰能力。 As an integrated temperature transmitter, it can directly output a 4-20 mA signal at the industrial site, which not only eliminates expensive compensation wires , but also improves the anti-interference ability of the signal during long-distance transmission.
Transmitter components have high accuracy, low power consumption, wide ambient temperature range, and stable and reliable operation. And because of the silicon rubber seal structure, the transmitter is resistant to shock and humidity, suitable for use in harsh field environments.
With linearization correction function, thermocouple temperature transmitter has automatic cold junction temperature compensation function.
It has a wide range of applications.It can form an integrated on-site installation structure with thermocouples and thermal resistors, or it can be installed in testing equipment as a functional module.
