Pantech Instrument’s Difference Indicator, Model 804, are designed to display not only indication of two process inputs, but each input on demand too. They provide two alarms on difference of the inputs and provide an analogue output of 4-20 mA DC.
The equation of Analogue output = K1+K2(A-B) where K1 & K2 are constants and AB are inputs.
The instrument can be powered by either 110 V AC or 230 V AC or 24 V DC. The instrument is available in standard ¼ DIN housing of 96*96 mm suitable for panel mounting.
Low drift precision components are used for long term accuracy of the instruments. All instruments undergo a burn-in for better reliability.
