  Product Description:  
 
green_line
 
 

The ACT-1B Panel Tachometer Series (three models) operate from either a single pulse per revolution, ten pulses per revolution, or sixty pulses per revolution.

The ACT-2A and ACT-3 are front panel programmable for single or multiple pulses per revolution and for scaling. They may be used as Tachometers, Rate meters, Counters, and Totalizers.

The ACT Series Panel Instruments offer a fixed and floating decimal point and can be supplied with Remote Optical, Infrared, Laser, Proximity, and Magnetic Sensors, and are directly compatible with a TTL input and a 200mV to 50 Vac signal. The ACT-3 also has front panel programmable alarm set points, analog voltage and current, TTL and RS232 outputs. The ACT-3 offers more standard features than any other Panel Bench Top Tachometer available. All models - Universal Input, non-contact operation from optical, infrared, laser, proximity, and magnetic sensors or direct TTL and 200mV to 50 Vac signals.

> An array of sensors are aslo available from Monarch.

base

The ACT Series consists of three models -one tachometer and two tachometer/
ratemeter/
totalizers.

All feature universal input for two and three wire sensors providing signals of 0-5V TTL or 0-200 mVac to 0-50 Vac. All models operate from optical, infrared, laser, proximity or magnetic sensors and display in fixed or floating decimal point format. The ACT-3 provides the best user benefits of any panel instrument available today.

Features
ACT-1B (5-99,999 RPM)
• One pulse/revolution (ACT-1B) or 60 pulses/revolution (ACT-1B-60)
• Output options: 4-20 mA (12 bit), 0-5 Vdc (12 bit) or TTL pulse
ACT-2A (5-999,990 RPM)
• Front panel programmable
• One or multiple pulses/revolution, scaling or totalizing
• Minimum and maximum memory recall
ACT-3 (5-999,990 RPM)
• N.I.S.T. Traceable Certificate of Calibration included
• Simultaneous 4-20 mA, 0-5 Vdc (12 bit), TTL pulse and 2 Alarm outputs and RS232.
• Single event speed capture from start and stop pulses, in units such as MPH, cm/sec, etc.
Using one sensor -
rotational, loop or reciprocating motion
.Using two sensors -
linear travel.
