Data sheet differential pressure transmitter PS 27

Product catalog summary

Overview: The document provides detailed specifications and features of the PS 27 differential pressure transmitter, designed for basic applications in pressure measurement. It highlights the device's compact design, measurement range options, and installation flexibility.

Specifications:

Measurement Ranges: Offers both fixed and toggleable measurement ranges, including asymmetric options. Ranges can be selected via DIP switches.
Installation: Suitable for top-hat rail mounting and wall surface installation.
Output Options: Configurable output signals (0-10 V, 2-10 V, 0-20 mA, 4-20 mA, 0-5 V) with DIP switch adjustments.
Power Supply: 24 V AC/DC or 15-32 V DC for two-wire technology.
Display and Relay: Optional 4-digit display and relay with changeover contacts (max. 230 V AC, 6 A).
Accuracy: ±3% for ranges <100 Pa, ±2% for ranges ≥100 Pa.
Environmental Conditions: Rated temperature range of -20 to 60°C, storage range of -20 to 70°C.
Protection and Certification: IP 65 protection class, CE/UKCA certified.

Applications: The PS 27 is suitable for ventilation, air-conditioning, and various air handling processes. It is part of a broader range of products offered by halstrup-walcher for stationary differential pressure measurement.

Accessories: Includes options for silicone and Norprene tubing, Y-pieces, and push-in fittings for pressure connections.

Comparison with Other Products: The document compares PS 27 with other models like P 26, P 34, and P 29, highlighting differences in precision, scalability, and application suitability.

User Software: Free software is available for parameter setting, monitoring, and recording via USB or RS 232 interface, compatible with P 26, P 34, and P 29 models.
