Panel-Mount Electrically Actuated Counters with Output Relay

Wire these counters up to an electrical pulse-emitting switch, sensor, or encoder for use on machine tools, packaging machinery, or other equipment. They have two displays. One display shows a set point and the other counts incoming pulses. When the counter reaches the set point, an output relay sends a signal to another device. The signal can start/stop a process or trigger an alarm.

Panel-Mount Air-Actuated Counters


These counters register up to 600 pulses of compressed air per minute. Counts decrease as air hose length increases; the hose length should not exceed 2 1/2 ft. to reach 600 counts per minute. Pressure must drop to 0 psi between pulses.

Rotating-Shaft-Actuated Counters


Precisely count rotations by attaching these counters to clutches, couplings, rotors, or other rotating shafts.
Shaft rotation direction is the direction of rotation when you're looking at the counter from the end of the shaft.

Counters/Hour Meters

Keep track of time while counting events. Units have two displays: one that receives input from a sensor, encoder, or switch and another that counts hours.

Analog Multimeters

Measure rapidly changing electrical values with an analog display that shows the magnitude and rate of change more easily than a digital multimeter.
Multimeter is average sensing, so it takes accurate AC measurements when testing equipment that has a linear load and draws current in a smooth sine wave, such as standard induction motors.

Simpson Analog Multimeters

The analog display shows the magnitude and rate of change more easily than a digital multimeter when measuring rapidly changing electrical values. Simpson multimeters are known for their ruggedness and reliability.
These multimeters are average sensing, so they take accurate AC measurements when testing equipment that has a linear load and draws current in a smooth sine wave, such as standard induction motors.
