| New pressure sensors for heat pumpsMay. 04, 2009 - The company Kavlico in Minden, Germany has developed a new version of the PT250 pressure transmitter designed specifically for installation in heat pump systems. Incorporating a piezo-resistive sense element, these extremely rugged, all-welded, 304L stainless steel constructed devices have an integral pipe pressure connection that is welded at the pressure source (see documentation next page). According to EU 842/2006 Directive, heat pump applications using fluorinated greenhouse gases must be checked for leakage at least once every 12 months or every 6 months depending upon the gas quantity they contain. However, the directive shall not apply to equipment with hermetically sealed systems. And in that case this new PT250 bring the right technical response. Indeed, the PT250 from Kavlico does not utilize a gasket thereby complying with the EU 842/2006 Directive. By installing a PT250 transmitter in the heat pump system, a significant cost-savings is achieved by no longer having to monitor leakage rates, a big plus for the end-user. Heat pumps will make a major contribution toward Europe meeting its climate and energy challenges for renewable heating and cooling technology, and Kavlico newly designed transmitter will assist with this "GREEN", efficient energy solution.
