P32000 Isolated Sensor Transducer | SIL 2 / SIL 3 Functional Safety
Description
Universal transmitters for temperature, strain gauges and potentiometers - in a 6-mm housing with infrared interface and SIL approval.
- Universal usability from simple to challenging measurement tasks with all known temperature sensors, strain gauges, potentiometers, and similar sensors
- Convenient setting of all parameters via IrDA interface – uncomplicated, menu-guided adjustment also “on site” including archiving of the configuration data
- Intuitive configuration of the basic parameters – easily, without tools, using 4 rotary and 8 DIP switches
- Calibrated range selection without complicated adjustment
- Automatic detection of the sensor connection (2-, 3- or 4-wire)
- Simulation of any desired output values for correct installation/commissioning
- Protective separation according to EN 61140 – protection of the maintenance staff and subsequent devices against excessively high voltages up to 300 V AC/DC
- Functional safety up to SIL 2 (up to SIL 3 in the case of redundant configuration) with TÜV certificate – systematically devel-oped according to EN 61508
- High accuracy with innovative switching concept
- Reduced inventory – one transmitter covers all conceivable tasks
- Minimum space requirement in the enclosure – only 6 mm wide modular housing – more transmitters per meter of mounting rail
- 5-year warranty
The P32000 universal transmitters provide connection possibilities for all standard thermocouples, resistance thermometers, strain gauges, full bridges, resistors and potentiometers/resistive sensors. They can be flexibly adapted to the respective measuring task using DIP and rotary encoder switches or via an IrDA interface.
3-port isolation with protective separation up to 300 V AC/DC according to EN 61140 ensures optimum protection of personnel and equipment as well as unaltered transmission of measurement signals. The P32000 offer maximum performance in the smallest of spaces. Resistance thermometers can be operated in 2-, 3- or 4-wire configuration. The connection configuration is automatically recognized, adjustment is not required. All commercial thermocouples can be read with internal or external reference junction compensation. To detect mechanical quantities such as force or strain, strain gauges can be connected in full-bridge configuration.
The ability to connect variable resistors and potentiometers creates a wide range of application possibilities, for example in the field of displacement or position detection. Input voltage signals up to +/– 1000 mV are converted into 0/4 to 20 mA or 0 to 10 V standard signals. This enables low-cost implementation of current measurements using shunt resistors, for example.
Knick offers the P32000 transmitter with SIL approval for applications with high demands on functional safety. The requirements of EN 61508 were implemented through specially developed hardware and software. The implemented fail-safe concept makes use of structural measures at the device level (redundancy of system components) and diagnostic methods for selective fault detection. The product is SIL2 approved (EN 61508) by an authorized body (TÜV Rheinland). SIL3 in redundant implementations.
We look forward to hearing from you!
