JUMO CANtrans p ceramic pressure transmitter with CANopen output (type 40.2055)

Pressure Transmitter with CANopen Protocol
Part Number: CANtrans p
Call for pricing

Description:

Pressure transmitters are used to record relative and absolute pressures in liquid and gaseous media. The pressure transmitter operates as per the thick-film-DMS measuring principle. The basic material of the sensor element is aluminum oxide ceramic (Al2O3). The measured pressure value is digitalized and made available through the "CANopen" serial bus protocol for further processing (CAN slave). A number of additional useful functions are realized through the dS 404 device profile. All settings are possible via commercially available CANopen software tools.

Further transmitters equipped with a CANopen output: see data sheet 40.2056 (Pressure), T40.2057 (Pressure + Temperature) as well as T90.2910 (Temperature).

Features

  • Measuring ranges: 0.25 bar to 600 bar relative and absolute pressure
  • Linearized and temperature compensated measuring range
  • Measuring principle: thick layer sensor made of aluminum oxide ceramic
  • Elastomer sealed
  • Medium temperatures: - 20 ... + 85 °C
  • Measurement values in any units on the CANopen bus
  • Protection class: IP 67

Customer benefits

  • Sturdy for high mechanical loads
    Maximum process reliability is guaranteed by the components coming into contact with the medium being of stainless steel, the welded system not presenting any dead spots, the device being designed with the IP 67 protection class, and providing high vibration resistance (shakeproof). The capacitive ceramic measuring cell of aluminum oxide (99.9%) offers a long operating live and is overload resistant.
  • Compact and economic
    The small dimensions (Ø 27 mm x 65 mm) allow for flexibility with regard to installation positions. Wiring and installation are simple and optimize material consumption. Uniform parameterization and diagnosis of the entire CAN bus system, except the sensor level, entails savings during start-up and maintenance.
  • Process safe and reliable
    Redundant sensors and a permanent self-diagnosis offer maximized safety and reliability. The data is transmitted safe and interference-free from the sensor to the control system. Additional functions with linearization and scaling, measuring range monitoring, precise adjustment, fly back function relieve the PLC .

Applications

  • Wind turbines
  • Mobile hydraulics
  • Boiler construction
  • Medical technology
  • Packaging machines
  • Plastics processing
  • Mobile vehicles and plants
  • Track-bound vehicles

Technical features

  • 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 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 value is 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 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 PDO telegram contains the 32-bit measured value and the 8-bit status. 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 or node guarding can also be used to monitor the transmitter function.
  • 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.
