LIQUID PRESSURE TRANSMITTERS PTL Series

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, while PTL-Cool is designed for extreme conditions where condensation is a common problem. PTL-Cool has a two-layer protection for the electronics. For this reason, any condensation does not damage 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

## Technical details PTL-Cool

- Accuracy (from FS): ±1.0 %
- Supply voltage: 15...24 VDC/VAC
- Output signal: 0...10 V or 4...20 mA
- Protection standard: IP65, two-layer protection against condensation
- Pressure connector: G1/4 internal thread
- Ambient temperature: -40...60 °C
- Medium temperature: -40...50 °C
