Series DR 1226

Product catalog summary
Overview: The document describes the electronic pressure-gauge station, specifically the DR 1226 and DR 1226-K series, designed for use in refrigeration and heating systems, suitable for both gases and liquids.
Specifications:
  • Type: Piezoresistive
  • Measuring Range: Up to 60 barg
  • Output: 4-20 mA
  • Supply Voltage: 12-30 V DC
  • Protection Rating: IP 54
  • System: Two-wire
Functionality: The device uses a piezoresistive pressure sensor to generate a pressure-proportional bridge voltage, which is normalized to the measuring range and output as a 4-20 mA signal.
Technical Data:
  • Load: Max 400 Ohm
  • Accuracy: Class 1
  • Ambient Temperature: -20°C to +60°C
  • Weight: Approx. 2 kg
  • Dimensions: 380 x 146 x 96 mm
  • Compression Strength: Short-time 1.3 times the measuring range
  • Vacuum Resistance: High vacuum
  • Material: DR 1226 - GK-CuZn38A, DR 1226-K - 1.4541
Installation Instructions: It is recommended to mount pressure transducers on rigid walls to avoid mechanical vibrations. For adequate cooling or heating of the fluid, a ring syphon should connect the pipeline and pressure sensor. In extreme temperatures, a sufficiently long piping is advised.
Measuring Ranges: Various measuring ranges are available, from 0-1 to 0-60 bar for DR 1226 and -1 to 24 bar for DR 1226-K. Additional ranges can be requested.
Additional Information: The document includes a circuit diagram and notes that technical alterations are subject to change.

Elektronische Druckmessstation Electronic pressure-gauge station Poste électronique de mesure de pression Mit einem piezoresistiven Druckaufnehmer wird eine druckproportionale Brückenspannung erzeugt. Diese Spannung wird auf den entsprechenden Messbereich normiert und als 4-20 mA-Signal zur Verfügung gestellt A piezoresistive pressure sensor produces a pressureproportional bridge voltage. This voltage is normalised to the corresponding measuring range and is usable as 4-20 mA-signal. Un système piézorésistif de mesure crée une tension de pont proportionelle à la pression. Cette tension est adaptée...
