How to Choose the Right Monarch Sensor

for Measuring Speed (RPM) of Rotating Objects

 

Monarch's Industrial Speed Sensors
Sensors measure process parameters such as rotational speed in industrial automation and process-control applications. These sensors are essential tools for predictive maintenance to make environments safer, more efficient, and ultimately less costly.

Monarch sensors are compatible with many of Monarch’s strobes, tachometers, and paperless recorders. Our Sensor Compatibility Chart is a great source for guidance.

 

 

 

 

Things to consider when choosing a sensor:

What is the range of the RPM being measured?
How and where will the sensor be mounted?
In what environment will the sensor be used?
Will the sensor need a display of the RPM or convert the RPM signal to a proportional analog output? (See our ACT Series Panel Tachometers and F2A Series Frequency to Analog Converters).

We invite you to contact us to discuss your application and get the right sensors, displays or frequency to analog converters.

Monarch offers an extensive line of sensors to detect and measure Speed (RPM).


Monarch Speed Sensors:
 

Optical: remote sensors that use a piece of reflective tape as a target.
These sensors can use light sources such as LEDs, lasers, and sometimes incandescent bulbs and usually offer the most flexibility in mounting. Some can detect contrasting colors such as black/white, light/dark. Monarch optical remote sensors include our ROS, ROSMROS-HT, ROLS, RLS, and CSLS

Infrared: IR sensors use an infrared light source to detect contrasting color targets.
Using infrared LED light, the sensor senses reflecting infrared beams, looking for interruptions. An IR sensor can be used to measure RPM up to 1,000,000/RPM interruptions. Monarch's IRS is ideal for applications providing light/dark surfaces or beam interruptions by solid objects as small as 030 in. [1 mm].

Magnetic: sensors that use a ferrous metal target. 
Amplified and non-amplified versions are available which have a bearing on the distance from the face of the sensor to the metallic target. This type of sensor is our MT-190 and M-190.

Proximity: sensors that are used to detect metallic targets.
Proximity sensor targets are usual bolt heads or shaft keys. Suitable for harsh industrial environments, these types of sensors are our P5-11 and PS-12 Proximity Sensors.

Self-Powered: sensors used to obtain a pulse output from many of our sensors to generate a trigger signal for RPM for equipment like vibration data collectors or data acquisition systems. They provide proper power for the sensor and a TTL type output on a BNC Connector. Examples are our SPSR-IM with many of our remote sensors and the SLS (Smart Laser Sensor) which has its own built in laser sensor.
