SUBMERSIBLE PRESSURE TRANSMITTER NAL 8838

Product catalog summary

Overview: The document is a technical datasheet for the Trafag Submersible Pressure Transmitter NAL 8838, designed for applications in shipbuilding, process technology, and water treatment. It highlights the transmitter's features, technical specifications, and ordering information.

Applications and Features: The transmitter is suitable for pressure ranges starting from 100 mbar and does not have media-contacting O-rings. It offers options for chemical-resistant materials, such as titanium, and lightning protection according to IEC 61000-4-5 standards.

Technical Data: The measuring principle is piezoresistive, with a media and ambient temperature range of -5°C to +50°C. The output signal options include 4-20 mA and 0-10 VDC. The device is approved by GL and KRS.

Ordering Information: The type code 8838 includes various configurations for measuring range, sensor type, pressure connection, electrical connection, and output. Custom pressure ranges and cable lengths can be specified upon request.

Specifications: The electrical data specifies supply voltage requirements and load conditions. Environmental conditions include a protection rating of at least IP68, withstanding humidity up to 95% relative, vibration up to 6 g, and shock up to 50 g. Mechanical data includes materials like 1.4435 (AISI316L) or titanium for wetted parts and housing.

Accuracy and Performance: The accuracy is defined by NLH (non-linearity and hysteresis) with different sensor types offering ±0.5%, ±0.25%, and ±0.1% FS. Temperature coefficients and long-term drift are also specified.

Dimensions and Additional Information: The document provides dimensions for standard and lightning-protected models, along with cable specifications. Additional resources such as data sheets, instructions, and flyers are available on the Trafag website.
