HK Instruments PTL Series Pressure transmitters for liquids

HK Instruments PTL series pressure transmitters serve the purpose of detecting pressure in liquid environments within heating and cooling systems. Specifically, the PTL-Heat variant is tailored for pressure detection in non-condensing scenarios, like district heating or heat recovery systems. Conversely, the PTL-Cool model is engineered to withstand extreme conditions where condensation is prevalent, boasting a dual-layer protection system for its electronics to prevent damage from potential condensation. Additionally, both variants within the PTL series are applicable for use with refrigerants and non-corrosive gases.

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

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