Installation Instructions
Bulletin 873P Programmable 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 should be
performed to assure that transmitter
operation is restricted to a safe
operating distance from the sensor
equipment and its wiring.
ATTENTION: If a hazardous condition can
result from unintended operation of this
device, access to the sensing area should
be guarded.
Description
Bulletin 873P Programmable Ultrasonic Sensors are
self-contained solid-state devices designed for noncontact
sensing of solid and liquid objects.
These sensors have two programmable setpoints with
sourcing (PNP) outputs that can be configured for either
normally open or normally closed operation. The setpoints
can be programmed to switch the discrete output at any
target position within the sensor’s range. In addition, they
also feature either a 4--20mA or 0--10V DC analog output
depending on the model. The slope of the analog output is
scaled between the limits of the setpoint values.
Programming of the setpoints and the output configuration
is done using the setup pushbutton on the rear of the
housing. These devices can be useful for many applications
including: level control, diameter measurement, distance
measurement, and presence detection.
