PST Air Probe

PST Air Probe (2.0m Lead)

The PST (Thermistor) Air Probe is a damped air probe for use with the RF600 Wireless Transmitters. The probe is connected to a 2.0m lead.

The PST (Thermistor) 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 Explained

It is fair to say, that any probe that can measure temperature, could be used as anAir Probe, with varying degrees of success. However,Air Probesare specifically designed for this purpose and so have a higher degree of accuracy and response.

Air Probesare often designed to be 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 high degree of accuracy.

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, hence havinga Damped Air Probe. For example, when you place a probe inside a fridge or freezer, you probably don’t want an alarm going off every time someone opens the door.

TheDamped Air Probesdo a good job of reflecting the temperature of samples in the fridge or freezer.SRF600 Wireless Transmitterare your early warning notification for any alarms, it would be unsuitable if ‘false alarms’ were constantly being raised.
