Bulletin 873P Ultrasonic Proximity Sensor

IMPORTANT: Save these instructions for future use.

IMPORTANT: Solid state devices can be

susceptible to radio frequency (RF)

interference depending on the

power and the frequency of the

transmitting source. If RF

transmitting equipment is to be used

in the vicinity of the solid state

devices, thorough testing s hould be

performed to assure that transmitter

operating distance from the sensor

equipment and its wiring.

ATTENTION: If a hazardous condition ca

result from unintended operation of this

device, access to the sensing area should

be guarded.

Description

Bulletin 873P Ultrasonic Sensors are self-contained

solid-state devices designed for noncontact sensing of solid

and liquid objects. They are available in several sensing

ranges with either an analog or discrete output depending

on the model.

The discrete output models have a normally open PNP

output that is switched when the target is within range.

They have a four-turn potentiometer to adjust the far limit of

the sensing range in order to ignore background targets.

The analog output models provide an output current or

voltage that varies linearly with the target distance within its

specified sensing range. Analog models are equipped with

either 4--20mA or 0--10V DC outputs. These devices can be

useful for many applications including: level monitoring,

diameter measurement, distance measurement, and web

tension.
