PU21 / PI21 - pressure transmitter

Product catalog summary

Overview: The document provides technical specifications for the pressure transmitters PU21 and PI21, designed for measuring relative pressures ranging from 0 to 100 bar. These devices feature a ceramic measuring cell and are noted for their excellent long-term stability and compact design.

Specifications:

Pressure Range: 0 to 1 bar up to 0 to 100 bar relative.
Process Connection: G1/2" thread.
Output Signal: PU21 offers 0 to 10 V in three-wire technology, while PI21 provides 4 to 20 mA in two-wire technology.
Supply Voltage: 13 to 30 Vdc.
Electrical Connections: Right-angle connector according to DIN 43650.
Protection Class: IP65 according to EN 60529.
Temperature Range: Medium temperature from -40 to +125 °C, ambient temperature from -40 to +85 °C.
Dimensions: Diameter 28 mm, length approximately 97 mm including plug.
Weight: Approximately 220 g.
EMC Compliance: Tested according to EN 61000-6-2, EN 61000-6-3, CE marked.

Performance:

Error Tolerance: Total error is less than 0.5% including non-linearity and hysteresis.
Temperature Drift: Zero point drift is less than 0.2% and span drift is less than 0.15% within 0 to 85 °C.

Pressure Ratings: The document includes a table detailing maximum excess and bursting pressures for various measurement ranges, ensuring the devices are vacuum-tight.

Product Variants:

PU21: Item no. 7720, requires customer-specific presetting, output of 0 to 10 V, 3-wire technology.
PI21: Item no. 7730, requires customer-specific presetting, output of 4 to 20 mA, 2-wire technology.

Conclusion: The PU21 and PI21 pressure transmitters are robust, versatile devices suitable for a range of industrial applications, offering reliable performance and compliance with relevant standards.
