JUMO CANtrans pT - Pressure and Temperature Transmitter with CANopen Output (402057)

Features

  • Measuring ranges: 0 to 250 mbar up to 0 to 400 bar relative pressure, 0 to 600 mbar up to 0 to 25 bar absolute pressure
  • Linearized and temperature-compensated measuring ranges
  • Measuring principle: piezoresistive or thin-film (strain gauge)
  • Stainless steel measuring cell, fully welded (no seals)
  • Integrated temperature sensor: PT1000
  • Temperature of medium: -50 to +125 °C
  • Measured values transmitted in any units to the CANopen bus
  • Protection type: IP67

Customer benefits

  • Robust to withstand high mechanical loads
    Excellent process reliability is guaranteed by the combination of protection type IP67, a high level of vibration resistance, parts in contact with media that are made of stainless steel, and a front flush, welded system. The stainless steel measuring cell is safe and reliable due to its long-term stability and high overload resistance. 
     
  • Compact and economical
    The small dimensions (Ø 27 mm × 65 mm) allow a flexible installation position with simple wiring and assembly, while optimizing use of materials. Uniform parameterization and diagnosis of the entire CAN bus system down to the sensor level results in savings during startup and maintenance. 
     
  • Compatible
    The device profile has been developed and designed in accordance with the CiA DS 404 standard. LSS is supported for setting the module ID and the baud rate. To allow for easy operation, the setting can be configured using a standard software tool. 
     
  • Process reliability
    Redundant sensors, a heartbeat function, node guarding, and continuous self-diagnosis provide excellent reliability. The data is transmitted from the sensor to the control system quickly and without interference (pressure sampling rate: 1 ms, temperature sampling rate: 250 ms). Additional functions with linearization and scaling, measuring range monitoring, fine adjustment, and the drag indicator function relieve the load on the PLC.


Technical features
 

  • The analog signals of the pressure measuring cell and temperature sensor are digitized.
  • The pressure and temperature signals are adjusted digitally at the factory.
  • The sensor monitoring continuously checks that the sensor signal function is correct and triggers high-priority emergency telegrams in the event of an error.
  • The pressure measured value can be scaled to any desired measuring units (or as a percentage of the measuring range). The temperature can be switched from °C to °F.
  • The fine adjustment features an auto-zero function and a freely adjustable characteristic line offset.
  • Undesired signal fluctuations can be suppressed using the adjustable filter constant.
  • The measured values are output with a choice of decimal place.
  • The measuring range monitoring has a choice of upper and lower limits. The result is output as a status byte along with the measured value in the PDO telegram.
  • The drag indicator function saves the minimum and maximum pressure and temperature measured values.
  • The date and name of the last maintenance operation can be saved.
  • The emergency telegram is triggered in the event of a sensor fault.
  • The two PDO telegrams contain the 32-bit measured value and the 8-bit status for pressure and temperature respectively. The measured value output can be controlled through various trigger conditions.
  • SDO telegrams can be used to set parameters and to request measured values and statuses.
  • The heartbeat signal can be used to additionally monitor the function of the transmitter.
  • The sync command can be used to also control measured value transmission.
  • The NMT telegrams are used to control the operating status of the transmitter.
  • The CAN module ID and the CAN baud rate are set either with LSS or SDO.

Applications

  • Wind power units
  • Mobile hydraulics
  • Boiler engineering
  • Plastics processing
  • Mobile vehicles and plants
  • Railway

Description

This pressure and temperature transmitter is used to record relative and absolute pressures in liquid and gaseous media. In addition, the integrated temperature sensor measures the temperature of the medium directly at the pressure diaphragm. The temperature transmitter receives the measured values from a Pt1000 sensor.
The pressure transmitter operates according to the piezoresistive or thin-film strain gauge measuring principle.

The pressure and temperature measured values are digitized and made available for further processing through the "CANopen" serial bus protocol (CAN slave). A number of additional useful functions are achieved with the DS 404 device profile.

For more transmitters with CANopen output: see data sheet 402055 (Pressure), 402056 (Pressure), and 902910 (Temperature).
