PTE-OI
Outside air temperature/illuminance sensor for HVAC applications
PTE-OI is a combination of a passive temperature and an illuminance sensor engineered for HVAC applications. PTE-OI is used to sense outside air temperature and ambient lighting conditions. In addition to the outside air temperature, the PTE-OI includes an ambient illuminance sensor. The illuminance sensor is hermetically sealed for protection.
PTE-OI is available with the following sensor types: • NTC10k • NTC20k • Pt1000 • Ni1000 • Ni1000-LG • NTC1.8k
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
RH-O – Outside Mount RH & T Sensor
سنسور دما و رطوبت فضای باز
A valuable feature of this sensor is when in 3-wire mode it automatically detects what the controller input is set to, 4-20mA or 0-10Vdc. This removes the requirement for output jumpers that can be inadvertently set incorrectly. 2-wire loop powering selectable via DIP switch. It also provides on board LED indication for power status and fault find.
- High stability and reliability
- Auto detection 0-10Vdc or 4-20mA outputs, loop powering via DIP
- LCD Display option
- Easy installation: 2-part, push-in spring terminal blocks
