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).
- 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
- 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 .
