TPK-04LS is a Thermocouple Surface Probe. It is mainly used to measure the surface temperature of metal. More detailed information for type K thermocouple probes. How to choose sensor accessories for thermometers? Generally, there are three types of temperature sensors on the market: thermocouples, platinum resistors and thermistors. > Thermistor: has a lower precision level and can be used as a temperature control or temperature protection device. It is not suitable for temperatures above 100°C and has poor stability. > PTC positive temperature coefficient / NTC negative temperature coefficient / CTR critical temperature coefficient, negative temperature thermistor with switching characteristics > Thermocouple T/C: Generally used between 100 degrees C and 1,000 degrees C, suitable for medium and high-temperature measurements, but the price is relatively low. Two homogeneous metal conductors are used to form a closed loop. When the temperature difference at the joint point causes an electromotive force to be generated in the loop. Using the Schiebeck effect, a temperature-sensing device formed by two metals and the joints at both ends is called a thermocouple. > Platinum Resistor (RTD): With a positive temperature coefficient, high accuracy, and stability, PT100 is often used at low temperatures < 0 degrees C or high temperatures > 100 degrees C, although its usable range is between -200°C ~ +600°C The temperature value is detected by utilizing the characteristics of the metal's resistance value due to temperature changes. The materials used include platinum, copper, nickel, etc., which can be divided into PT100/JPT100/PT200/PT 500, among which PT 100 is the most widely used. Our company can provide a DTM-385. DTM-386 temperature recorder > Different thermometers must be matched with different temperature wires or measuring rods. Otherwise, the temperature measurement values will be inaccurate. > If the range you are using is a general temperature range such as -90 ~ 1 to 200 degrees C, the T-type is a good choice because its temperature deviation is small and stable. Our company's DTM-507 is a variety of thermometers.
