Temperature is a well-known ancient concept. With the rapid development of science and technology, temperature has become a fundamental parameter in industrial monitoring and control systems. Temperature transmitters are commonly used as temperature measurement methods in the industrial field, and are suitable for temperature measurement in liquid or gas and process industries. However, due to the particularity of temperature, we use temperature sleeves to protect temperature transmitters and their probes in some high-temperature media and complex environments. Today we will take a look at the changes in some technical parameters of temperature transmitters when adding sleeves. The casing of the temperature transmitter is made of 304 stainless steel material, which has good corrosion resistance. The weight of the casing of the temperature transmitter varies with length. The sleeve length of conventional temperature transmitters can be divided into several cases: 35mm, 85mm, 135mm, 185mm, and 285mm. The weight of 35mm casing is 120g, 85mm casing is 130g, 135mm casing is 140g, 185mm casing is 150g, and 285mm casing is 170g, When measuring a temperature transmitter with a sleeve, it is important to note that the pressure borne by the thermal protection tube of the temperature transmitter changes with length, and the pressure resistance performance also changes accordingly. The specific parameter changes are shown in Figure 1:

The range of medium flow rate that the temperature transmitter protection tube can withstand will also decrease with the increase of insertion depth, and the specific change curve is shown in Figure 2

It should be noted that when using a sleeve, the response time of the temperature transmitter will increase. If you want to improve the response time of the temperature transmitter with a sleeve during on-site use. Thermal conductive media can be added to the casing of the temperature transmitter. To improve the response time of the temperature transmitter. If your on-site working conditions require the use of temperature transmitters with sleeves, then the above parameters must be understood and familiar to us.
