| （2）Main technical parameters 1、Operating temperature: platinum thermistor - 200~600 ℃, copper thermistor - 50~150 ℃ | | 2、Tolerance | | Graduation mark | Grade | Graduation mark ℃ | | A | ±(0.15+0.002│t│) | | B | ±(0.30+0.005│t│) | | Cu100 Cu50 | B | ±(0.30+0.006│t│) |
| 3、Insulation resistance: when the ambient temperature is 25 ± 10 ℃ and the humidity is ≤ 80%, the insulation resistance shall be ≥ 100M Ω 4、Insertion depth：100～1500mm 5、Time constant: protective tube ф 12、 ф 16 ≤ 90s, tapered pipe ≤ 180s | （3）Model, characteristics and scope of application
As a temperature measurement and regulation sensor, it is usually used to match with the display instrument to directly measure the temperature of liquid, steam, gas and solid surface in the production process. It has the advantages of convenient maintenance and low price, but it has poor shockproof performance and should not be inserted too long. |  |
