PFT28Ka

Die Kabelsonde komplettiert die Produktgruppe der Klimamessumformer PFT28

The climate transmitter PFT28 has already proved its worth in years. It is available in various product versions and to round up the application package we have added a cable version. From now on, our PFT28 is delivered with a cable probe (connected by a 2 m cable). This variant is particularly suitable for example in storage rooms, cold-storage rooms and working areas or in the air conditioning / ventilation duct, industrial process monitoring, drying processes, air conditioning and test chambers.

In addition, the PFT28 can also be used in the high-humidity range. Due to the internal heating element, the sensor is actively protected against condensation in a very high humidity environment. Furthermore, the protection against dust and direct moisture has been improved with an optional protective filter directly on the sensor element.

- Measurement of temperature and relative humidity

- Digital signal transmission from the sensor to the evaluation electronics

- Response time of a few seconds

- Easy interchangeability of the sensor

- Alphanumeric LCD display

- Analog outputs 0/2...10 V or 0/4...20 mA

- Supply voltage 15...30 Vdc or 24 Vac (± 15%)

- Compact plastic housing Protection class IP54; UL 94 HB

- Measuring range relative humidity 0 ... 100% (short term condensation possible)

- Measuring range temperature -30...+ 50 °C, 0...50 °C, 0...100 °C

- Calculation and display of dew point temperature, enthalpy wet bulb temperature and absolute humidity

The transducer PFT28Ka converts the measured variables of temperature and relative humidity into the following parameters: dewpoint temperature, absolute humidity, moisture ball temperature and enthalpy.

The device has two analog outputs: Output 1 supplies the temperature signal and one of four further measured variables can be applied to output 2 via two-pole DIP switches.

For direct display of the measured value, measured value and unit, the device has a two-line alphanumeric display.

Different versions are available:

A room sensor for wall mounting, a duct sensor for installation in a ventilation duct and a cable management variant with 2 m cable. In both versions, the sensor tube is installed directly on the housing. The output signals can be switched from 0/2 ... 10 V to 0/4 ... 20 mA with a plug-in bridge. The device is supplied with 15 ... 30 Vdc or 24 Vac.
