What types of sensor outputs can be interfaced with my Electro-Sensors equipment?
The standard output being used with Electro-Sensors equipment is NPN Open Collector type. However, much of our equipment can be interfaced with other sensors that are not manufactured by Electro-Sensors. Consult Factory on specific equipment and sensor details, or refer to product data sheets on this web-site.

How do I calculate frequency or Hertz (Hz)?
Frequency is measured in Hertz. Hertz is the measure of pulses per second. Hertz is calculated using the following equation:

    Hertz = (PPR)(RPM)/60

Where PPR = Pulses Per Revolution
RPM = Revolutions Per Minute

What is the maximum operating temperature for Electro-Sensors products?
When specified, our sensors, discs, and wraps can be used in areas up to a maximum of 302° F. Our Electronics are rated to 122°F. Consult Factory with exact application concerns.

Is my 4-20mA or 0-10V output isolated?
Most of our current products (SA420, TR400, TR5000, CT6000, MS320, MicroSpeed 196, MS332) have an isolated output. Isolator cards (CVI-50 for example) may be purchased for other equipment.

What if I need to return my product for credit/repair?
Contact Electro-Sensors, Inc. for details and Return Policy @ 1-800-328-6170. All products being returned must have a Return Authorization Number (RA#).
