![]() If the temperature changes, the internal pressure of the temperature gauge with probe will change as well. The measuring system itself is filled with a liquid. When is an expansion temperature gauge suitable?Īn expansion temperature gauge consists of a temperature probe, a capillary and a Bourdon tube, and is also suitable for temperature measurement at remote measuring locations. +1,112 ☏) in accuracy classes 1 and 2 in accordance with EN 13190. Bimetal temperature gauges are available with a measuring range of -70. If one end of the bimetal measuring system is firmly clamped, the other end will rotate the pointer shaft. Through the mechanical deformation of the bimetal strips in the aforementioned tube types, a rotational movement results, caused by temperature changes. The measuring system consists of two sheets with different expansion coefficients, which are inseparably joined. How does a bimetal temperature gauge work?īimetal temperature gauges operate with a measuring system in the form of a helical or spiral tube. The most widely used measuring methods for temperature measurement rely on temperature-dependent characteristics of the body and substance. The measuring system must be brought as closely together as possible with the body to be measured. Temperature gauges measure the thermal state of a homogeneous substance. ![]() gas-actuated thermometers | What's the difference?". You can learn more about the differences in our video " Bimetal vs. Which measurement principle should be used depends on a number of different factors, such as response time, temperature limits & application range. In industrial temperature measurement, primarily two types of dial thermometers are used: bimetal and gas-actuated thermometers. All instruments are also suitable for operation in thermowells. They can measure measured values between -200 … +700 ☌ (-328. WIKA offers professional temperature measuring instruments using the gas-actuation, bimetal or expansion principle.

If your vehicle needs a thermostat replacement, engine repair, coolant leak repair, or any other auto services, please do not hesitate to bring your car to Ward Tirecraft. You should stop running your car and call for a tow immediately. If your temperature gauge is reading high, the car is likely overheating, which is a grave matter. While a cold reading may indicate a problem, it is typically not as severe or concerning as a hot reading. If this is the problem, you will need to replace the thermostat. With the thermostat remaining open, the engine can be overcooled. Another explanation for a consistently cold reading is if the thermostat in the vehicle stays open.If the temperature gauge continues to point towards cold after the engine has heated up, the gauge may be damaged.This is considered normal and happens in the cold winter. On most automobiles, the temperature gauge will typically read cold until the engine has run for several minutes. Why the Temperature Gauge May Be Reading Cold Lastly, your temperature gauge can read hot due to water pump damage, which a mechanic can fix with a replacement.You may need a coolant temperature switch replacement if this is the scenario. A high reading in some cases may mean that your thermostat is broken.A minor leak should be diagnosed and patched up by an auto professional. Another reason it might be high is that you have a coolant leak ( that could lead to engine overheating). ![]() If your temperature gauge reads hot, there’s a possibility that your engine is overheating.Why the Temperature Gauge May Be Reading Hot This dial is often overlooked, but it is important to understand what it means if it fluctuates too low or hot. This indicator will let you know if your engine’s coolant is cold, normal, or overheating. The temperature gauge, most often located on your dashboard in your vehicle, is intended to show the temperature of your engine’s coolant. ![]()
