What is a body surface temperature and pressure?

What is a body surface temperature and pressure? Why it is called a surface temperature and pressure? What is the working principle of temperature and pressure of a surface? Below by the instrument to solve for you: a body surface and high water temperature and pressure meter is can also indicate temperature and pressure, can do a multi-purpose table, its working principle is: when the temperature changes, due to the bimetallic strip of the materials of the two different linear expansion coefficient is relatively large and produce different expansion and contraction, leading to a bimetallic strip bending deformation, the amount of deformation of different produce different momentum, momentum transfer drive connection shaft, shaft drive at the other end of the indicating needle, indicating pointer is just on the correct reading, indicate the temperature. To introduce a WHT - below 2 b a body surface temperature and pressure: WHT - 2 b water meter high use areas: industrial, petroleum, chemical, heating system, pipeline, water heater, heat preservation box, machinery, pharmaceutical, food, water treatment, etc. Description: specifications: WHT - 2 b type: temperature and pressure meter integrated structure, the axial type material: black electric pan, direct screw-plug PC transparent cover surface diameter: 71. Sheath maerial of 5 mm diameter: 6. 35 mm copper connections: 1/4 & quot; NPT heat pipe length: 37. Teeth 5 mm, with extended parts: 25 mm square temperature range: 20 - 160℃, ℉ pressure range: 0 - : 75 psi/FeetH2O precision temperature: + / - Pressure: 2% + / - 3 - 2 - Table: 3% glass product features: the scene display temperature, intuitive and convenient; Safe and reliable, long life, fast reading. Use note: the temperature and pressure of a surface when use should pay attention to clean up and check, regularly test the measured values.
