Integrated temperature transmitter

A summary of integrated temperature transmitter

SBW series integrated temperature transmitter is a temperature sensor (thermal resistance or thermocouple) and temperature transmitter module unit combined together, With a very simple way to -200~+1600℃ range of different temperature of the thermal resistance or thermocouple temperature signal into two wire system 4~20mA DC current signal transmission to display, regulator, recorder, DCS or direct RS485 communication, to achieve the precise measurement of temperature and remote control. The integrated temperature transmitter has the field display type and the non-field display type according to the user's request, the integrated temperature transmitter is the modern industrial field, the scientific research institute temperature measurement and control instrument's updating product, is the distribution system, the digital bus system's necessary product.

Two, the characteristics of integrated temperature transmitter

1, A, modular type of ultra-small module (module Φ44 ×18) integration, strong versatility (conventional analog type, with RS485 communication type, HART protocol type), conventional analog type can achieve two channel transmission signal output.

B, integrated circuit transfer unit, field display and output can achieve different measurement and control requirements: a, a display, all the way output (conventional);

B, a display, two output;

C, two display, two output

2, the use of DC24V power supply, two-wire system 4~20mA DC output or RS485 communication function, the transmission distance is long, strong anti-interference ability.

3, cold end, temperature drift, nonlinear automatic compensation.

4, high measuring accuracy, good long-term stability, display transmission accuracy: 0.5, 0.3, 0.2, 0.1 (fully isolated intelligent integrated temperature transmitter); Sensor accuracy: thermal resistance A (PT100); Thermocouple class I class II

5, The temperature module adopts epoxy resin pouring process, which is suitable for all kinds of harsh and dangerous places.

6, Integrated design, simple and reasonable structure, can directly replace the ordinary assembly type thermocouple, thermal resistance.

7, mechanical protection IP65.

8, the use of thermocouple temperature change, can avoid the use of compensation wire, reduce costs.

9, can be equipped with liquid crystal, digital tube, pointer and other field indication functions, convenient on-site observation and timely monitoring.

10. When the field ambient temperature is >60℃, the temperature sensor and the display instrument of the field transmission unit can be installed by split type (isolation).

11, explosion-proof grade: ExdIIBT4 ~6, ExdIICT4 ~6

12. Protection grade: IP54
