Series 26Y Piezoresistive Water Level Transmitter.

Series 26Y Piezoresistive Water Level Transmitter.

Quick Overview

The Series 26Y are pressure transmitters used in water level measurements that require considerable accuracy but at a competitive price. Ranges from 200 mBar up to 10 bar (corresponding to water column depths of 2 m to 100 m), sealed at 1 Bar or vented. Available with standard voltage and 4-20mA current outputs and a 5ms start up time makes the Y Series transmitters excellent for remote, or low power, datalogging applications.

The Series 26Y use a monocrystalline silicon measuring cell behind a 17mm stainless steel diaphragm and protective plastic cap. The Y-series electronics of the sensor has a very low start up time, less than 5ms, making it ideal for remote data logging application.

PAA-26Y Absolute, Zero at Vacuum

This probe is used in conjunction with a separate barometric pressure sensor to allow the readings to be adjusted for the atmospheric pressure and an accurate water level to be calculated as the difference between the absolute value and the ambient pressure. Cable material Polyolefin (PE-based), or PUR cable.

PR-26Y Transmitter, Zero at atmospheric Pressure

This probe is fitted with durable cable with an integral vent tube to the atmosphere and will provide a true water level compensated for atmospheric pressure. These level transmitters can be subject to internal condensation caused by installations in cold water on warm, humid days. If the reference tube is not terminated in a warm, dry enclosure, the use of a purpose built cartridge filled with a silica gel will prevent moisture in the reference tube. Cable material Polethylene (PE) with vent tube.
