American concept engineering heat flow sensors are used in greenhouses and soils; insulation evaluation of walls, roofs, etc .; biomedicine; submarines and ships, etc. General heat flow sensor
The general heat flow sensor F-020-4 produces a slight temperature difference on the sensor. This temperature gradient is proportional to the heat flow. A plurality of micro thermocouple junctions (thermopile) arranged in an appropriate manner in the heat flow sensor generates an electromotive force (mV) output. The electromotive force (mV) output is multiplied by the correction constant to obtain the heat flow value.
General heat flow sensor F-020-4 can choose to include T or K type thermocouple to measure the temperature.
Technical parameters of general heat flow sensor F-020-4:
Heat flow range: 3000 BTU / tfHr or 9.5 KW / m2
Time constant (63%): 14 seconds
Temperature range: -50 ° C ~ 150 ° C or -58 ° F ~ + 300 ° F
Thermal conductivity: 0.18 BTU / ft Hr ° F or 0316 W / m ° K
Accuracy: +/- 5%
Linearity: +/- 2%
Calibration: Each sensor is marked with a sensitivity constant (NIST traceable)
Environmental resistance: waterproof, not affected by pressure or vacuum
Heat flow direction: two-way response
Ironing Board Cabinets are cabinets for ironing and storing clothes. They are usually made of stainless steel, solid wood (wood fragrant board, solid wood particle board, MDF), tempered glass, and hardware accessories. Generally, cabinets, door panels, silent wheels, and door curtains are used as components. Built-in clothes rails, trouser racks, pull baskets, disinfection lamps and other accessories, using punching, assembly, riveting, welding and other processes, with flame retardant, anti-rodent, seamless anti-cockroach, dust, moth, moisture, clean Beautiful, easy to move and other functions, there are large-capacity intelligent disinfection Ironing Board Cabinet, glass Ironing Board Cabinet without power supply, stainless steel Ironing Board Cabinet, ultraviolet disinfection and cleaning Ironing Board Cabinet, moisture-proof multi-functional Ironing Board Cabinet, men's and women's lockers, dry cockroach-proof Ironing Board Cabinet, folding Ironing Board Cabinet, and simple Ironing Board Cabinet. Commonly divided into flat doors, sliding doors inside and outside the cabinet, etc., the plates used in wardrobes are generally stainless steel, metal, wood, etc., and are one of the commonly used furniture in households.
The general Ironing Board Cabinet is made of 18mm thick materials (particle board, MDF, solid wood board, composite multi-layer board, finger joint board); Plates, louvers, painted panels" or 5mm glass sliding doors; swing doors are generally made of 16mm or 18mm materials); in general, hardware is a matching tool for Ironing Board Cabinet manufacturers, and they do not produce it themselves. There are also a few businesses that produce hardware for Ironing Board Cabinet themselves.
