JUMO CANtrans T RTD Temperature Probe with CANopen Output

High-Precision Digital Signal Processing

The internal measuring insert utilizes a Pt1000 sensor in a two-wire circuit, providing a sampling rate of 250 ms. The digital processing architecture allows measured values to be directly output in degrees Celsius, Fahrenheit, or Kelvin, with user-selectable decimal places (0, 1, or 2).

Comprehensive Device Functions (CiA Profile DS 404)

Adhering to the CiA DS 404 profile, the probe offers extensive auxiliary and monitoring functions accessible via standard CANopen software tools and EDS object directories:

• Sensor Monitoring: Continuously checks sensor integrity and triggers high-priority emergency telegrams in case of a probe break or short circuit.

• Filter & Scaling: Adjustable filter constants suppress undesired signal fluctuations, while scaling functions adapt the output to custom measuring units.

• Min/Max Indicator: Integrated drag indicator functions save minimum and maximum measured temperature peaks.

• Fine Adjustment: Features a freely adjustable characteristic line offset.

Rugged Mechanical & Electrical Build

The unit is housed in a vibration-resistant stainless steel (1.4571) protection tube and process connection, ensuring a reliable seal against underpressure and overpressure. Electrical connection is established via a reliable 5-pole M12x1 round plug (IEC 60947-5-2), yielding an IP67 protection rating when screwed on.

FAQ

Q1: How do I configure the parameters and baud rate of the CANtrans T?

A: All device parameters, module IDs (1 to 127), and baud rates can be easily set using standard CANopen software tools via LSS, SDO, or the device object directory (EDS file).

Q2: What is the difference between basic type 902910/10 and 902910/12?

A: Basic type 902910/10 is the standard RTD temperature probe design, whereas 902910/12 includes an extension tube specifically engineered to handle higher operating temperatures up to +450 °C safely.

Q3: Does the probe provide error detection if the sensor fails?

A: Yes. The built-in sensor monitoring continuously checks sensor functionality and automatically triggers high-frequency emergency telegrams and status flags in the event of a probe break or short circuit.

Q4: What kind of electrical connection does the sensor use?

A: The unit features a standard 5-pole M12×1 round plug (complying with IEC 60947-5-2), which achieves an IP67 waterproof and dustproof protection rating when properly screwed on.
