P143

Product catalog summary

Performance Features:
The Combi Sensor P143 features a polypropylene housing and offers a wide range of pressure measurements from 0…250 mbar to 0…20 bar. It provides high accuracy (≤ 0.5%) and various analog outputs (4…20 mA, 0…10 V, etc.). Optional features include integrated PT100/PT1000 sensors for temperature measurement and a stainless steel cap for use as a level sensor.

Applications:
Suitable for chlorine and saltwater applications, chemicals, gaseous media, water, wastewater, wells, and aggressive media. It can function as a level sensor or screw-in transmitter with a G 1/2 in. thread and IP68 protection.

Technical Data:
The sensor operates on a piezoresistive principle, ensuring long-term stability (≤ ±0.5% FS/year) and quick response time (50 ms). It supports a wide temperature range (-25…80 °C for medium and surrounding, -40…85 °C for storage) and offers electrical protections like short-circuit resistance and reverse polarity protection.

Electrical Connection:
The sensor supports various output configurations and requires specific power supplies depending on the output type. For cable lengths over 30 m, shielded cables are recommended.

Accessories and Options:
Available accessories include a stainless steel cap and M12 connector. The sensor can be customized with different process connections, output signals, sensor seals, cable materials, and lengths.

Measuring Range:
The sensor covers a wide range of pressure measurements, detailed in the provided table, with overload protection specified for each range.

Ordering Code:
The ordering code allows customization of the sensor with options for process connection, output signal, measuring range, sensor seal, cable material, and additional options like stainless steel cap and M12 connector.

Dimensions:
Detailed dimensions are provided for both the level sensor with stainless steel cap and the screw-in transmitter version.

Datasheet Combi Sensor P143PERFORMANCE FEATURESPP housing (Polypropylene) ■ Smallest measuring range: 0...250 mbar / 0.2,5 mH2O ■ Largest measuring range: 0.20 bar / 0.200 mH2O ■ Optionally integrated PT100 / PT1000 Sensor for temperature measurement ■ Optionally with stainless steel cap usable as level sensor The model P143 can be used as a level sensor or as a screw-in transmitter. The screw-on stainless steel cap provides the necessary weight to prevent floating during level measurement and at the same time protects the diaphragm. Without the cap, the device can be used as a screw-in transmitter with G 1/2 in. thread, integrated seal and protection class IP68. The measuring cell operates based on the piezoresistive principle and forms, in combination with the polypropylene housing, a slim transmitter with high chemical resistance. Our modular design concept provides a wide variety of products. Feel free to contact us if you need a customization that is not listed in this datasheet.
