The endothermic glass is a flat glass that absorbs a large amount of infrared radiant energy and maintains a high visible light transmittance. There are two ways to produce endothermic glass: one is to add a certain amount of colorant with endothermic properties to the raw material of ordinary soda lime silicate glass; the other is to spray one or more layers on the surface of flat glass. Made of metal or metal oxide film. The heat absorbing glass is gray, brown, blue, green, bronze, bronze, pink and golden. At present, China mainly produces the first three colors of heat absorbing glass. There are four thicknesses of 2, 3, 5, and 6 mm. The heat absorbing glass can be further processed to be polished, tempered, and laminated to form an insulating glass. The heat absorbing glass can also block sunlight and cold air, making the room warm in winter and cool in summer. The heat absorbing glass has the following characteristics compared with ordinary flat glass: 1 absorption of solar radiant heat For example, a transparent float glass of 6 mm thickness has a total permeation heat of 84% under sunlight, and the total permeation heat of the endothermic glass under the same conditions is 60%. The color and thickness of the heat absorbing glass are different, and the degree of absorption of solar radiant heat is also different. 2 absorption of solar visible light Reduces the intensity of sunlight and acts as an anti-glare. 3 has a certain transparency Can absorb certain ultraviolet rays. Due to the characteristics mentioned above, the heat absorbing glass has been widely used in doors and windows, exterior walls of buildings, and as a windshield for vehicles and boats, and functions as heat insulation, anti-glare, lighting, and decoration. Absorbing part of the sun's visible light softens the glaring sunlight and acts as an anti-glare. The visible light transmittance and direct sunlight transmission rate of 5mm different color heat absorbing glass in China are shown in the following table. Color visible light transmittance /% direct sunlight transmittance /% Brown ≥45 ≤60 Gray ≥30 ≤60 Blue ≥50 ≤70
Temperature transmitter is an instrument that converts a temperature variable into a transmittable standardized output signal. Temperature transmitters convert physical measurement signals or ordinary electrical signals into standard electrical signal output or devices that can output in the form of communication protocols. A temperature transmitter is an instrument that converts temperature variables into a transmittable standardized output signal, and is mainly used for the measurement and control of temperature parameters in industrial processes. The current transmitter is to convert the AC current of the main circuit under test into a constant current loop standard signal, which is continuously sent to the receiving device
Features of the temperature transmitter:
1. Two-wire output DC4-20mA current signal, strong anti-interference ability;
2. Save the cost of compensation wire and installation of temperature transmitter;
3. Large measurement range;
4. Automatic compensation of cold junction temperature, non-linear correction circuit.
Applications of temperature transmitters:
Usually used with display instruments, recording instruments, electronic computers, etc., widely used in petroleum, chemical, chemical fiber; textile, rubber, building materials; electric power, metallurgy, medicine; food and other industrial fields for on-site temperature measurement process control; especially suitable for computer measurement and control The system can also be used in conjunction with the instrument.
Temperature transmitters make it possible to send a scaleable (4 to 20) mA signal from a Temperature Sensor to a control device without investing in long, expensive runs of thermocouple or RTD wire.
Pyromation carries programmable RTD and thermocouple temperature transmitters that can be mounted in the temperature sensor assembly connection head, or surface mounted using a DIN rail mounting clip. Some units offer a visual digital display that shows the current measured value. All are PC programmable and convert various signals into a scaleable (4 to 20) mA analog output signal. We also carry transmitters programmable with Hart® protocol for various signal inputs. Depending on type, some of Pyromation`s thermocouple and RTD temperature transmitters are UL recognized components and/or FM and CSA approved, including styles that are intrinsically safe and approved for use in hazardous locations.
Pyromation temperature transmitters are used in many demanding industries including Pharmaceuticals, Oil & Gas, Power Generation, Chemical, PetroChemical, and Food and Dairy.
