Part No: SRFAX200D
The PST Air Probe Duplex is a damped, dual air probe with a 2.0m lead for use with SRF Wireless Transmitters.
The PST Air Probe Duplex is a damped, dual air probe for use with SRF600 Wireless Transmitters. Each probe is connected to a 2.0m lead.
The PST Air Probe Duplex 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 an Air Probe, with varying degrees of success. However, Air Probes are specifically designed for this purpose and so have a higher degree of accuracy and response.
Air Probes are 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.
That said, all Setra Air Probes for SRF600 are inherently designed to be slow. Why is this? Read on to find out….
We supply a Damped Air Probe style for the SRF600 Wireless Transmitters, which comes in the form of a small stainless steel bullet-shaped end, see picture.
This type of construction has two purposes;
In certain scenarios, it is beneficial to have a slower response to changes in air temperature, hence having a 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.
The Damped Air Probes do a good job of reflecting the temperature of samples in the fridge or freezer. The SRF600 Wireless Transmitters are your early warning notification for any alarms, it would be unsuitable if ‘false alarms’ were constantly being raised.
