JUMO CANtrans p pressure transmitter with CANopen output (type 40.2056)

Funktioner

• Measuring ranges: 250 mbar to 100 bar relative and absolute pressure
• Linearized and temperature compensated measuring range
• Measuring principle: piezoresistive or thin film (DMS)
• Stainless steel measuring cell, completely welded
• Medium temperature: - 40 ... +125°C
• Optional high temperature version up to 200 °C (SIP and CIP compatible)
• Measured values in selectable units on the CANopen bus
• Protection class: IP 67

Kundefordele

• 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).
• 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..

Technical features
 

• The analog signal of the pressure measuring cell is digitalized with a 12 bit resolution.
• The pressure signal is digitally factory-adjusted.
• The sensor monitoring continuously checks the correct function of the sensor signal and triggers emergency telegrams in the event of an error.
• The measured pressure value can be scaled to any dimensional unit (or to % of the measuring range.
• The precision adjustment system includes an auto-zero function as well as a freely settable characteristic curve offset.
• Undesired signal fluctuations can be suppressed by the settable filter constant.
• The measured value is shown with a freely selectable decimal point.
• The measured value monitoring feature has freely selectable upper and lower limits. The result is put out as a status byte next to the measured value with the PDO telegram.
• The fly back function saves the minimum and maximum measured pressure value.
• Date and name of the last maintenance can be saved.
• The emergency telegram is triggered in the event of probe defect.
• The PDO telegram contains the 32 bit measured value as well as 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 inquire measured values and status.
• The transmitter functions can also be monitored with the heartbeat signal or with node guarding.
• The sync command allows the additional control of measured value transmission.
• The NMT telegrams are intended to control the transmitter operating status.
• Setting of the CAN module ID and of the CAN Baud rate is optional through LSS or SDO.
