The electronic pressure switches series KD5 and ATR141 work in conjunction with the input signals 4> 20mA or 0> 10Volts. Their function is to continuously display the value of pressure or temperature with the possibility to set alarm thresholds. The installation for both is a panel for electrical panels for the series ART141 while for the series KD5 with IP65 degree of protection can be installed on panels with drilling diameter 63mm instead of the traditional gauges. The series KD5 can also measure the difference between two signals 4> 20mA.
