Data Sheet ECTR 8471

Product catalog summary

Overview: The document is a technical data sheet for the ECTR 8471 Economic Refrigeration Pressure Transmitter by Trafag Sensors & Controls, Switzerland. It outlines the specifications, applications, features, and ordering information for the product.

Applications: The pressure transmitter is suitable for HVAC and refrigeration applications, offering economical solutions with good media compatibility. It supports both relative and absolute pressure measurements, with an optional titanium version.

Features: Trafag is a Swiss-based supplier known for high-quality sensors and monitoring instruments. The transmitter features a thick film on ceramic measuring principle with typical accuracy of ±0.5% FS at 25°C.

Technical Specifications:

Measuring Range: -1 to 9 bar up to 0 to 40 bar (0 to 15 psi up to 0 to 500 psi).
Media Temperature: -25°C to +125°C.
Output Signal: Options include 4-20 mA, 0-5 VDC, 1-6 VDC, 0-10 VDC, and 0.5-4.5 VDC ratiometric.
Ambient Temperature: -25°C to +85°C (PVC cable: -5°C to +60°C).

Ordering Information: The type code 8471.XX.XX.XX.XX.XX specifies various configurations including pressure range, pressure connection, electrical connection, and output signal. Extended overpressure and customized pressure ranges are available upon request.

Electrical Data: The transmitter supports various supply voltages depending on the output signal, with rise time typically at 1 ms for 10-90% nominal pressure. It includes inverse-polarity protection and short-circuit strength.

Environmental Conditions: The device operates within a media temperature range of -25°C to +125°C and an ambient temperature range of -25°C to +85°C. It is protected to a minimum of IP65 and can withstand vibrations up to 4g and shocks up to 50g.

Mechanical Data: The sensor is made of ceramic (Al2O3, 96%) with a housing/pressure connection of 1.4305 (AISI303). It includes various sealing options and weighs approximately 110 g.

Additional Information: The document provides links to additional resources such as data sheets, instructions, and flyers. It also details electrical connections and protection standards.
