Descriptions Of Trafag ECTN 8477 Marine Pressure Transmitter
The economic pressure transmitter ECTN 8477 is based on the tried and true ECT line of transmitters.
The wide media temperature range from -25 to 125°C in combination with a comprehensive set of features and options makes the ECTN 8477 pressure transmitter a versatile solution suitable for marine applications.
A pressure transmitter developed especially for maritime use, the Trafag ECTN 8477 satisfies industry standards for dependability under challenging conditions. The transmitter is a great option for hydraulic systems, engine control, and other maritime applications because it provides precise pressure measurement, long-term stability, and corrosion resistance. International marine certifications including DNV, GL, and ABS are met by the product.
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.
Main Features of Trafag ECTN 8477
- Measuring ranges from 100 mbar
- Excellent media compatibility
- Relative or absolute pressure measurement
- Titanium version optional
