Profile: Kaif Digital Corp. is a manufacturer of process control equipment. Our product line includes controllers, indicators and monitors. Our PPM series accepts a linear voltage, current or millivolt signal at its input, converts it into desired engineering units, and then displays it. In addition, it also monitors a number of useful functions such as high and low process readings, change in process value from any given point, process run time, and rate of process change. The input signals are displayed in engineering units that correspond to the process being monitored; e.g. if measuring pressure, the input signal can be scaled to give the reading directly in PSI. Scaling is accomplished from the front keys and does not require any tedious formulas. Also offered is a tare function for weighing and any similar applications. The programmable counter/rate monitor is a highly versatile instrument that is capable of working as an up/down counter, rate, rpm, or frequency monitor. Selection of different operating modes is easily accomplished from the front keys. The unit features four preset alarms (optional), which can be ordered with relay or open collector outputs. Also featured are two timers (optional) which come with open collector outputs.
