JFA621 LED display oil temperature switch transmitter
Widely used in hydro-power,
tap water, petroleum, chemical,
This temperature measurement and control product which integrates temperature measurement, display,
output and control.The product is a full electronic structure. The front end adopts a piezoresistive temperature
sensor or ceramic piezoresistive sensor with isolation film. The output signal is amplified by a high-precision,
low-temperature drift amplifier and fed into a high-precision A / D converter. It is converted into digital signal
which can be processed by microprocessor. The signal processed by operation controls two switches to
measure and control the temperature of the control system.
◆ 4 digits display temperature value
◆ Temperature preset switch point and delayed switching output
◆ The outer shell is equipped with a node-operated light-emitting secondary tube, which is easy to observe.
◆ Key adjustment and field setting of various parameters,easy operation.
◆ 1-2 switch output, overload capacity 1.2A,the switch quantity can be set arbitrarily between zero point and full degree.
◆ PNP,NPN,4～20mA output optional.
