They are available in many different designs to suit pressure and electrical connections, measuring procedures, electrical output signals, and certifications (CE, EX, rail, and ship).
About Pressure Transmitters
Pressure transmitters are electronic pressure gauges and are used to measure and monitor pressure. The term pressure transmitter is also often used for pressure transducers or pressure sensors. However, this is not a synonym, since the term pressure sensor in the narrower sense only describes a part of the pressure transmitter.
Descriptions of Trafag NAH 8254 20 Khz Pressure Transmitter For Highly Dynamic Pressure Curves
A special combination of thin-film on-steel sensor elements with the in-house developed ASIC enables high-dynamic measurements. Recording of highly dynamic pressure curves with the NAH 8254 in a small space is possible, e.g. to analyze the opening and closing performance of valves, track pressure curves of explosions and explosive pressure expansions or to examine brief pressure peaks in hydraulic systems.
Main Features of Trafag NAH 8254 20 Khz Pressure Transmitter
- Cut-off frequency 20 kHz
- For highly dynamic pressure curves
- Analogue signal processing
- Measuring accuracy 0.3 %
- Excellent long-term stability
