Our Products
We offer a complete product range of Digital Temperature Controller and Blind Temperature Controller
setpoint and process both are displayed simultaneously. the process display is 12.5mm height.the setpoint display is 8mm height. the power supply is 90-260 vac.
notes1. on-off control: relay is on upto the set temperature and cuts off at the set point. system temperature will come down and again relay will go on at temperature 2 c below the set point. same function is repeated. adjustable dead band is provided for specific application. time-proportionating control : relay will be on and off in band of 2 c of set-point. on-off : time will adjust as per the heat requirement of the system. of course total time cycle will be of 15 seconds. 2. 4 digit temperature indicator/controller nippon 2020a.3. contact factory for supply volts of 90 - 260 vac & retransmission output
principle : input signal is signal conditioned, linearised and amplified. it is compared with the set point and accordingly relay operates.
