Profile: Cixi Shengan Electro Co., Ltd. designs, develops & manufactures differential pressure switches, burglar alarm serials and other products. Our products include pressure switch serials, alarm serials, shell of fire call point, fire detector DOS shell, module DOS shell, gas alarm DOS shell, and temperature sensor. SA101 series differential pressure switches can sense the pressure difference, vacuum, over pressure, and poor flow of the non-corrosive gas. The switch is preferably mounted with the diaphragm in a vertical plane, unless the device is set or calibrated for horizontal mounting, as on special customer models. On these models, the mounting position is indicated on the side of the control. It may be fastened directly to the duct, heater or panel, as long as the mounting surface has minimal or no vibration. Pressure connections are marked with + (high pressure ) and - (low or static pressure). SA-001 temperature sensor uses NTC thermal sensitive resistors as temperature sensing component. Its characteristics are high sensitivity, good stability, anti-corrosive, long life, and can be assembled conveniently. Adapted to any high and low temperature & humidity ambient, it can sense the temperature of air and water fast & accurately, then send the signal to the controlling system, so as to control the temperature accurately.
