The DX28L Damped Sensor Probe (Thermistor) is fitted with a 6-Pin Lumberg connector with locking screw, to provide a strong and secure probe-to-instrument connection with better prevention of liquid ingress.Not suitable for intrinsically safe applicationsAir Probes ExplainedIt 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 Comark Air Probes for RF500 for example, are inherently designed to be slow. Why is this? Read on to find out….We supply a Damped Air Probe style for the RF500 Wireless Monitoring System (and other thermometers), which comes in the form of a small stainless steel bullet shaped end, see picture.This type of construction has two purposes;It protects the sensor from physical damageIt slows the response of the probe down significantlyIn 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 samples in the fridge. All Damped Air Probes are fitted with a 6-Pin Lumberg Connector and a stainless steel Damped Air Probe end, as shown below.Technical SpecificationsNameValueSensor TypeThermistor (PST)Connector Type6-Pin LumbergTemperature Range-40°C to +70°C / -40°F to +158°FSystem Accuracy with Comark Thermometers±0.5°C -20°C to +70°C / ±0.9°F -4°F to +158°FResponse Time30.0 secondsLead Length2.0mLead MaterialFEPWarranty6 MonthsArticles / FAQsNameDate My Probe is stuck in the Lumberg connector?My Probe is stuck in the Lumberg connector?If you are using a Probe, connected to your device via a 6-Pin Lumberg connector and the Probe appears to be stuck in the connector, then it may have been over-tightened.You should initially try to release the screw thread connector gently.To prevent the connector from locking in the future, you could use food safe grease on the connector threads. This problem may also be prevented by keeping the instrument clean when in use.If this does not work, you will need to return your instrument for service. 20th April 2015 General Care of Temperature ProbesGeneral Care of Temperature ProbesThe Probe is where most of the action with any Thermometer takes place. Almost every operation requires a Probe reading. The Probe should be treated with care in order to ensure best functioning and long life.We would recommend that you always have a spare, properly functioning Probe on hand, just in case the primary Probe breaks, or appears to be reading incorrectly.You should not stretch the coiled cable of any Probe, to reach an item to be measured. We would recommend instead that you ALWAYS move BOTH the Probe and the Thermometer, toward the food to be measured. This will help avoid unnecessary stress on the wires inside the Probe.You should not touch the coiled cable or Probe handle to hot surfaces, that might melt the protective coatings, which in turn could damage the Probe wires and render the Probe inoperable.You should not bend the tip of any Penetration Probe, as this too could break the wires and render the Probe inoperable. In general, Penetration Probes are designed for penetrating thawed food only and not for testing frozen food or containers or chipping ice.You should clean the Probe and wire coil with a clean damp cloth, being VERY careful not to pull or stretch the coil and damage the wires inside.
