Compact High Pressure Transmitter Series 310

Product catalog summary

General Overview
The miniature pressure transmitter is designed for installations with limited space, offering small dimensions and excellent performance.

Description
The transmitter features a 30mm housing with a sputtered thin film sensor and electronics. It can withstand severe pressure peaks with a proof pressure of 3 times the full scale (FS). The unit offers various electrical outputs and connections, making it versatile for different applications. Its stainless steel construction ensures durability.

Technical Data

Input: Measuring span ranges from 0 to 5 bar up to 2,200 bar gauge. Proof pressure is 2 times the nominal pressure (PN) up to 1000 bar and 1.5 times PN above 1600 bar. Burst pressure varies from 10 times nominal up to 400 bar to 1.8 times nominal above 1600 bar. The fatigue life exceeds 100 million cycles.
Output: The output signal is linear with a conformity of 0.15% of nominal pressure. Hysteresis and repeatability are ±0.1% of full scale deflection. The response time is less than 4 ms, and long-term drift is 0.1% per year.
Power Supply: Direct current with a supply voltage up to 30 V. Current consumption is 4.5 mA to 20 mA.
Ambient Conditions: The permissible ambient and process temperatures range from -40 to +125 °C. The compensated temperature range is -40 to +120 °C. The device is CE approved for electromagnetic compatibility.

Dimensions and Connections
The transmitter is compact, with a build-up of approximately 35 mm. It offers various pressure ports and electrical connections, including M12 x 1,5, G ¼ A, and others. The housing is made of stainless steel 316 L, with protection modes IP 65 and IP 67 depending on the electrical version.

Mounting and Accessories
Mounting position is not critical, but care must be taken to allow displaced volume to escape in liquid-filled systems. For temperatures above 120 °C, a syphon is recommended. The transmitter can handle pressure spikes with a restrictor or damping device. The maximum mounting torque is 30 Nm, and the weight is approximately 35 g without a connector.

Order Codes and Accessories
Various cables and connectors are available for different electrical connections, with specific order codes provided for each type.
