高精確防爆型液位傳送器 Series 36 XW Ei

For Hazardous Applications

These piezoresistive pressure transmitters are approved for use in high explosive gas and dust atmospheres of groups I (mining industry) and II (industrial applications) where there is a high risk of explosion. Optionally available are Low Voltage Versions (LV) with 3,5…8,5 V.

Signal processing:
This series features microcontroller-based electronic evaluation to ensure maximum accuracy. Each transmitter is gauged across the entire pressure and temperature range. This measurement data is used to calculate a mathematical model that enables correction of all reproducible errors. In this way, KELLER can guarantee high accuracy as an error band within the overall compensated pressure and temperature range. Two compensated temperature ranges are available for industrial transmitters, according to choice: -10…80 °C and 10…40 °C. The level probes are gauged in the 0…50 °C temperature range only. The calculated pressure value can be read via the interface, and is simultaneously processed as an analog signal.

Interface:
The interface is designed as a robust RS485 half-duplex for 9'600 and 115'200 baud. There is an external leadthrough for the interface on all products except the version with the DIN 43650 plug.

Options:
- Low Voltage Version labelled with “LV” in Type Designation
- Mining Version labelled with “M” in Type Designation
- Dust approval
