Pressure level transmitter Level sensing relative and absolute pressure transmitter Type 713 The pressure level transmitter type 713 is used for continuous fluid level measurement of ground and drinking water. The compact design allows the transmitter to be used in applications with restricted access as small as ¾ inch i.d. pipe. As well as a current output the pressure level transmitter type 713 has been enhanced with energy efficient ratiometric and digital outputs making it ideal for battery powered applications. The pressure level sensor 713 is based upon the well proven ceramic technology developed by Huba Control over 20 years ago. + Ceramic sensor Al2O3 99.6% + Continuous level measurement + Suitable for drinking water + Available with integrated temperature measurement + Applicable in ¾ inch pipes + Excellent linearity and long term stability Huba Control Type 713 | Technical data subject to change | Edition 09/2020
