PTL

Pressure transmitters for liquids

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 non-aggressive gases.

 

PTL-Heat series devices are commonly used in HVAC/R systems for:
• District heating
• Liquid heat exchangers
• Heating substation
• Air compressor systems

PTL-Cool series devices are commonly used in HVAC/R systems for:
• District cooling
• Fan coil units (FCU)
• Chilled beams
