ThermoTrans A 20210

Temperature Transmitter

  

Standard transmitters for temperature measurement in a 6 mm housing using resistance thermometers or thermocouples.

Facts and Features

  • Flexible use
    with common temperature sensors: Pt100, Pt1000, Ni100, type J and K thermocouples
  • Intuitive configuration
    easy, without tools, using 4 rotary and 8 DIP switches
  • Calibrated range selection
    without complicated adjustment
  • Automatic detection
    of the sensor connection (2-, 3-, or 4-wire)
  • Protective separation
    according to EN 61140 – protection of the maintenance staff and down-stream devices against excessively high voltages up to 300 V AC/DC
  • High accuracy
    with innovative switching concept
  • Minimum space requirement
    in the enclosure – only 6 mm wide modular housing – more transmit-ters per meter of mounting rail
  • Low-cost assembly
    quick mounting, convenient, connection of power supply via DIN rail bus connectors
  • 5-year warranty 

 

The Task
In virtually all areas of industry, temperatures are continuously measured and often used as a reference input for closed-loop control systems, monitoring systems, safety shutdown systems, or for similar critical jobs.
As a rule, high demands are placed on function, accuracy, flexibility and electrical safety. Different sensors are used depending on the measuring task. They provide a raw signal which is prepared, linearized and standardized for further processing using a temperature transmitter

The Problem
The range of standardized and commercial temperature sensors is extremely broad. The large number of sensors, connection variants, individual temperature ranges, different supply voltages, and required output signals call for very flexible transmitters that can be optimally suited to the different conditions.
However, the required flexibility should not come at the price of complex operation. Rather, being able to easily make adjustments on site is desirable. High performance should not result in increased susceptibility – high reliability and availability are essential.

The Solution
The flexible ThermoTrans A 20210 temperature transmitters provide connection possibilities for most of the common thermocouples and resistance thermometers. They can be flexibly adapted to the respective measuring task using DIP and rotary encoder switches. 3-port isolation with protective separation up to 300 V AC/DC according to EN 61140 ensures optimum protection of personnel and equipment as well as unaltered transmission of measuring signals. The ThermoTrans A 20210 offer maximum performance in the smallest of spaces.
Resistance thermometers can be operated in 2-, 3- or 4-wire configuration. The connection configuration is automatically recognized, adjustment is not required. Thermocouples can be detected with internal or external reference junction compensation.
Input voltage signals up to ±1000 mV are converted into standard 0/4 to 20 mA or 0 to 10 V signals. This enables low-cost implementation of current measurements using shunt resistors, for example.
Special measuring tasks can be solved with ThermoTrans devices which Knick configures according to individual specifications. Fixed-range devices without switch are used, for example, when manipulations or mix-ups must be precluded.
