Targets hygienic applications including medical equipment, food and chemical processing, and bottling and packaging

By Alex Pluemer, contributing writer

Hoffman and
Krippner claims one of the smallest ultrasonic sensors with the introduction of
the P53-80-D18, measuring 45 mm long
with an 18-mm diameter. The new sensor’s size and reliable performance in harsh
conditions make it a good fit in a variety of hygienic applications such as
medical equipment, food and chemical processing, and packaging.

The sensor can be
used to measure distance, detect presence, detect objects in motion, count
objects, and check for completeness. It features a special V4A stainless-steel
housing construction (1.4404) with a roughness depth of 0.6 μm, making it
resistant to moisture, water vapor, dust, and other particulates. The sensor
and the mounting assembly can be sanitized with strong cleaning agents without
degrading the device, further enhancing its utility in hygienic applications.


The P53-D18,
along with the P53-SC-D18-5-EHEDG support clamp, meet the European Hygienic
Engineering and Design Group’s (EHEDG) “hygienic equipment design criteria” for
“Type EL, Class I Aux” for mechanical design, composition, and surface
qualities. The sensor should be used in conjunction with the accompanying
P53-SC-D18-5-EHEDG support clamp for applications with strict hygienic
requirements. By using ECOLAB-certified materials the sensor provides
resistivity against cleaning agents like P3-topactive OKTO, P3-topactive 200,
P3-topax 52, P3-topax 66, and P3-topax 990.

The miniature P53
offers a range of up to 800 mm and operates in temperatures as high as 80°C. The
sensor is outfitted with an integrated cable screw connection for hygiene in
food and beverage as well as bottling and packaging industries. The industrial
version includes an M12 connector with a power supply, signal output, and teach-in
and can be mounted with two Teflon nuts that provide acoustic decoupling. Also,
the P53 can be configured via the M12 connector cable. Optional hold/synch
switches are available.

P53-80-D18 is available now. Data
sheets and additional tech details
are available.
