Pressure Sensors Transducers Procurement Notes

Verify the complete ordering code against official Trafag documentation to ensure correct configuration of electrical connections and process interfaces. Confirm that the specific suffix codes match the required output signal type and housing material. Cross-reference the pressure range and overpressure limits with system requirements to prevent damage during operation.

Pressure Sensors Transducers Selection Notes

Select this model when both analog signal transmission and discrete switching are required simultaneously. Ensure the operating pressure does not exceed the rated 100 psi limit. Verify compatibility with the available 15-30 V DC power supply. Check that the 1/4" NPT port size fits the existing piping infrastructure without requiring adapters.
