  • How to check a faulty temperature sensor? Sometimes sensors can break or degrade in harsh environments. Below is a guide to check issues with thermocouples and resistance thermometers to diagnose various failure modes to help you rectify the situation. The first indication that a thermocouple or pt sensor is not working correctly will be from the instrument it is connected to. The readings might appear lower or higher than expected or the instrument will be showing an error code.

    Instruments connected to a thermocouple or pt will often be a temperature controller or a readout. Different errors on a controller will mean different things depending on the brand and model. Thermocouple readings do change if leads are not correctly connected. Check for any thermocouple cable wiring issues Incorrectly wired compensating cable Incorrect wiring of thermocouple cables can be further complicated because thermocouples often use compensating cable.

    It is possible that the compensating cable is incorrectly wired to the thermocouple. It may appear correctly wired at the instrument but not correct between the thermocouple and compensating cable. Using the wrong compensating type Each compensating cable is also tied to a specific thermocouple type. To ensure accuracy you must only use compensating cable of the same type e. Sometimes other types of cable such as general instrument cable, or copper cable is used to extend thermocouples and this also creates errors.

    Using compensating cable in high temperature environments The final quirk with compensating cable is that it should not be used in high temperature environments. Thermocouple compensating cable is rated for a lower temperature than thermocouple cable. Try to use compensating cable in ambient temperatures to reduce errors. Check for local heat source issues If your thermocouple is reading high, it could be because your sensor is located too close to a heat source.

    If your sensor is near a local heat source it could increase the temperature being measured as opposed to the position you wish to measure temperature. Check Temperature Transmitter Settings If your sensor is using a temperature transmitter it is important to check that the output of the transmitter and the input of the instrument is the same. Most commonly a signal range of 4…20 mA is used.

    Check temperature controller settings Check input settings on temperature controller For example, if you have your temperature controller setup for Type S input but attach a Type B thermocouple sensor it would display an incorrect temperature and lead you to believe your sensor was faulty. You will need to make sure the input selected on the controller matches the type of thermocouple or resistance thermometer connected to it.

    There are also a couple of controller errors that point to a fault in the temperature sensor. Instrument shows: Input signal higher or lower than limit Out of range error The controller could be displaying several things indicating that it believes there is an out of range error. Common brands of controller could show: Brand.

    You need to know how to get water out of a meat thermometer before your father-in-law discovers you borrowed his favorite thermometer. Relax — you might be able to get the water out without suffering catastrophic damage, family hunger and hits to your culinary savvy.

    However, the problem grows more complex if you need to get water out of a digital thermometer. Ions are electrically charged particles that can damage digital technology by creating short-circuits and making sensors malfunction.

    Tips for Preventing a Digital Thermometer from Getting Wet When Cleaning The best way to prevent water from getting into any thermometer is to clean it carefully. Some thermometers are fully submersible and dishwasher-safe, but you can prevent fogging and condensation by cleaning and sterilizing the instrument manually.

    Thermometers with small pieces and tight connections can be cleaned with Q-tips and rubbing alcohol. Rinse and dry the unit carefully after cleaning and disinfecting. For example, digital thermometers have a probe section and a controller unit.

    The probe needs more rigorous cleaning and disinfecting to prevent cross-contamination of foods. Tips to prevent getting your thermometer wet when cleaning it include: Wiping and disinfecting the probe after each use to prevent bacterial buildup Wiping the unit with a soft cloth and soapy water until clean Disinfecting the thermometer with disinfectant or a bleach-water solution using just a few drops of bleach in a small amount of water Rinsing carefully after disinfecting Handling the thermometer away from sinks or buckets of water to prevent it from falling into the water Storing your thermometer away from sharp kitchen tools that could pierce the unit Easy Steps for Removing Condensation from Your Digital Meat Thermometer If the water got into your thermometers, there are the steps for you to remove condensation from your digital meat thermometer.

    Turning off the thermometer. Place the probe or body — whichever part has condensation — in a casserole dish, and cover it. Bake in a preheated degree oven for 35 to 40 minutes. Note: If necessary, bake a little while longer. Ways to Remove Water or Condensation Of course, there are also some other strategies can help to remove water or condensation from your digital thermometer include recommendations from online readers. Try air-drying the thermometer in the sun and moving it regularly to different positions.

    The Rice Solution Plain white rice is one solution that often works with various types of thermometers. You place the thermometer in a covered container of rice. Rice absorbs water rapidly — even without cooking. Covered rice in a sealed environment will suck up any water or moisture available. You should start by leaving the thermometer in rice for a day, but you can extend the time up to a week. If nothing improves by then, this is not the solution. Water In, Water Out If water gets in, it can get out.

    The challenge is finding the right conditions to draw the water out or evaporate it. You can try heating the thermometer in a slow oven, drying it out in the sun or blasting it with warm air from a hairdryer.

    These are great ideas for how to get the moisture out of grill thermometers. Shining a Light on the Problem Some people report success by leaving the thermometer on top of an incandescent light overnight.

    Be careful about how you position the instrument, but the technique often works to dry the water gently. These are not guaranteed solutions — they work in some cases and not in others because the thermometer may already be damaged by the ions in the water. ThermoPro offers comprehensive warranty plans for one to three years, and the company will replace your thermometer if it becomes defective within the warranty period. How to Dry a Candy Thermometer Figuring out how to get water out of a candy thermometer can present a double challenge.

    Candy thermometers take more of a beating than any other type of thermometer. Candy — when cooked to the hard-crack stage — can cover your probe or thermometer with brittle candy and become impossible to clean by simple methods.

    After cleaning the thermometer, you can disassemble it as much as possible by removing the cap at the end. Stick the thermometer in a warm oven until dry. You can also try air-drying the assembly in the sun, using a hairdryer or sticking the thermometer in a sealed container of rice for a day or so. Alternatively, you can try this method of how to get condensation out of a candy thermometer. The candymaker gives tips for keeping your thermometer free of moisture and stuck-on candy.

    Conclusion The best way to deal with water intrusion is to follow the above recommendations. Buying a high-quality thermometer is also a good strategy.

    The first indication that a thermocouple or pt sensor is not working correctly will be from the instrument it is connected to.
