WTYY-1021 remote thermometer (pressure thermometer) and the serialized temperature meter developed thereby overcome the shortcomings of the traditional expansion thermometer with single performance, short life, poor reliability and large volume of the temperature package. The volume of the temperature measuring component is 30 and 60 times smaller than that of the conventional steam and gas pressure thermometer, and the platinum or copper thermal resistance temperature measuring component is creatively installed in the temperature measuring component, thereby realizing the mechatronics temperature measuring function. Formed a multi-function, serialized temperature meter with remote pressure, explosion-proof, anti-vibration, anti-corrosion, electric joint, temperature signal transmission, etc. Specification model:
1.WTY series thermometer numbering rules
2.WTY series thermometer number description
1. The number of the front slash "/" in front of the model part, according to the "Industrial Automation Instrumentation Product Model Writing Principles",
"/" is the specification part, which is stipulated by our factory. If the character is too long to be filled in the design selection, please contact us.
Other codes are agreed upon.
2. The meter function in the first section is the basic function. To select more than one function, please add the third section “Function Combination” in the number, among which the shockproof, electric connector and the highest indicator can only be selected. A function, the function of both explosion-proof and electrical connectors can not be combined.
3, additional instructions, please specify the soft tail material, the type and location of the outlet device, whether with protective casing, explosion-proof instrument outlet, hot spot resistance number and other content to be explained. For example: "WTY-1033-X2-F0 ~ 100 °C Φ12 * 300 * 10M content brake pipe Pt100 left junction box" means: the thermometer is a liquid pressure type live connector double upper limit alarm thermal resistance remote transmission thermometer, and with anti-corrosion cover The specific dimensions of the tube are: temperature package diameter 12mm, insertion depth 300mm, brake tube soft tail length 10M. Platinum thermal resistance Pt100, left junction box lead, mounting thread is ferrule thread M27*2. Basic technical parameters:
Temperature range: -40 to 600 ° C
Ambient temperature: -10 to +55 °C
Relative humidity: 5 to 95%
Indication accuracy: 1.5
Time constant: ≤60S
Probe shockproof: 6Mpa
Probe diameter: 8-10mm, movable external thread: M27*2
Thermal resistance PT100 (single, dual output) or 4-20mA current output
Thermal resistance indexing number: Pt100 or Cu50
Thermal resistance accuracy grade: ZBY-301-85-B
Thermal resistance thermal response time: τ0.5 = 35 seconds (45 seconds when Teflon is encapsulated) Performance:
(1) It has the characteristics of small temperature probe, high sensitivity, linear scale and long life.
(2) It has many functions such as remote transmission of resistance signal (PT100), shock resistance, corrosion resistance and high-power switching signal.
(3) The structural form is the same as that of the international similar products and can be used as an alternative to imports. Features:
The explosion-proof liquid pressure type thermal resistance remote transmission thermometer and the serialized temperature meter derived therefrom overcome the shortcomings of the traditional expansion thermometer, such as short life, poor reliability and large volume of the temperature package. The volume of the temperature measuring component is 30 and 60 times smaller than that of the conventional steam and gas pressure thermometer, and the platinum or copper thermal resistance temperature measuring component is creatively installed in the temperature measuring component to realize the mechatronic temperature measurement. Features. A multi-function, serialized temperature meter with long-distance transmission, explosion-proof, anti-vibration, electric contact, temperature signal transmission, etc. with liquid pressure type thermometer as the basic temperature measuring instrument is formed. Note:
1. The outlet device of the electric contact, the thermal resistance or the temperature transmitter is generally located at the lower part of the meter head, and the transmitter outlet device adopts the explosion-proof junction box outlet device.
2. Built-in and mounted explosion-proof thermometers, the junction box must be placed on the upper part of the temperature measuring element, and it is strictly prohibited to be placed in the lower part of the meter.
3, embedded and mounted intrinsically safe explosion-proof thermometer, the junction box is generally placed in the lower part of the meter, can also be placed on the upper part of the temperature measuring element as needed.
4. When the upper limit of the meter range is greater than or equal to 300 °C, the installation thread is made of stainless steel material, and the thread is installed to the head size h=100 mm; when the upper limit of the meter range is less than 300 °C, the installation thread is made of H62 brass h=60 Millimeter.
