Q.What Is A Ultrasonic Sensor?

Ans:

Ultrasonic sensor works on principle of High Frequency ultra-Sound Wave Propagation. It has very log sensing. Ex.distances up to 20 mtr. Ultrasonic Sensors are used for non-contact type distance measurement application.

Q.What Is A NAMUR Sensors?

Ans:

The NAMUR type sensor is intrinsically safe proximity switches designed to work in the hazardous areas. The working voltage & current levels of these switches are restricted to safe values as per standards. Also, It is non-amplified sensor that supplies two different signal levels depending upon switch state.These signal levels are low-level current. A logic interface circuit, controller, PLC, DCS, or intrinsically safe (IS) barrier is needed to read these current levels.

Q.What Is Universal Indicator?

Ans:

Universal Indicator shows corresponding value for any given parameter for 4-20 mA current input or 0-10 volts voltage input.. You can also set required scale with full scale value.

Q.How Infra Red Proximity Sensor Is Different Than Inductive Proximity Switch?

Ans:

Infra Red Proximity Sensor is actually Diffused Infra Red Sensor.

Q.What Is Potential Free Contacts?

Ans:

Potential Free Contacts this term is used for Relay Contacts. When Relay Contacts are not connected in any circuit, it does not have any voltage or potential at the contacts.  Hence Relay Contacts (NC - C - NO) without any connections are known as Potential Free Contacts.
