• Damped air probe
• Sensor type: PT100

The Comark RFAP100 PT100 Air Probe is a damped air probe for use with the Comark RF516 PT100 Wireless Temperature Transmitter. The probe is connected to a 1.0m lead.

The RFAP100 PT100 Air Probe is fitted with a 6-Pin Lumberg connector with a locking screw, to provide a strong and secure probe-to-instrument connection with better prevention of liquid ingress.

Air probes are often designed to have a very quick response with a low thermal mass. The sensor is designed to be as small as possible so that the air temperature is transferred to the probe with minimal temperature loss or gain to maintain a higher degree of accuracy. However, all Comark Air Probes for the RF500 systems are inherently designed to be slow.

Comark supplies a damped air probe style for the RF500 Wireless Monitoring System series, which comes in the form of a small stainless steel bullet-shaped end.

This type of construction has two purposes:

• It protects the sensor from physical damage
• It slows the response of the probe down significantly

In certain scenarios, it is beneficial to have a slower response to changes in air temperature. When you place a probe inside a refrigerator or freezer, you may not want an alarm going off every time someone opens the door.

The Damped Air Probes do a good job of reflecting the samples in the fridge. As the RF500 Wireless Monitoring System is your early warning notification for any alarms, it would be unsuitable if ‘false alarms’ were constantly being raised.
