FromProdual UK Ltd.
PTL series pressure transmitters are used for pressure detection in liquids in heating and cooling systems. PTL-Heat is used for pressure detection in non-condensing applications such as district heating or heat recovery systems, whereas. PTL-Cool is designed for extreme conditions where condensation is a common problem. PTL-Cool has a two-layer protection for electronics. This is why the possible condensation does not harm the product. PTL series products are also suitable for refrigerants and nonaggressive gases.
