The electrical resistance of metals changes in a certain proportion with temperature variations, allowing for temperature measurement. High-purity platinum is most commonly used due to its large temperature coefficient of electrical resistance as a metal material. The temperature measuring resistance using this platinum is called a platinum resistance thermometer (PT sensor). The elements of platinum resistance thermometers can be ceramic, platinum thin-film types, etc. ○When measuring, the self-heating phenomenon caused by the current flowing through the temperature measuring resistance is taken into account, and the following currents are specified based on the nominal resistance value. Nominal resistance value (R0 value) 100Ω, specified currents 0.5mA, 1mA, 2mA ○Wiring methods for temperature measuring resistance (PT sensor) There are 2-wire, 3-wire, and 4-wire configurations, with the 3-wire configuration being the most common. ○Classes of temperature measuring resistance (PT sensor) Class A = ±(0.15 + 0.002|t|) Class B = ±(0.3 + 0.005|t|)

Company information
Sanko Co., Ltd. manufactures and sells temperature sensors and electric heaters in Sakai City, Osaka Prefecture. We particularly produce cartridge heaters and micro heaters in-house, responding to various requests from our customers. If you have any issues related to heaters, please feel free to contact us. Whether you want to know the cause of a disconnection in your currently used heater or seek advice on how to extend the lifespan of your heater, we welcome any inquiries. In addition to heaters, we also manufacture temperature sensors such as thermocouples. Since we purchase materials cheaply from overseas, we can offer our products at competitive prices. We have a subsidiary in Thailand, where we manufacture temperature sensors like thermocouples, cartridge heaters, and micro heaters. If you would like to discuss purchasing heaters locally in Thailand, please feel free to reach out to us. In addition to cartridge heaters and micro heaters, we also handle seed heaters, rubber heaters, aluminum cast heaters, band heaters, plate heaters, aluminum immersion heaters, and quartz tube heaters.
