Toftejorg Sanitary Rotacheck Sensor.

Print   Print this page      Email   Email to a friend
Toftejorg Sanitary Rotacheck represents an important tool for
increasing quality assurance in tank cleaning, since it provides an
electronic means of verifying the 3D impact coverage of the Toftejorg
rotary jet head. The system is appropriate wherever rotary jet heads
are employed in cleaning tanks. The signal generated by the system
can be audible, visual or integrated into the customer's process control
specification. Toftejorg Sanitary Rotacheck is particularly suited to
industries where improved verification standards are required, e.g.,
PAT for pharmaceutical industry, food and beverage industries.
Working principle
The Toftejorg Sanitary Rotacheck sensor is precisely installed to detect
the sweep and impact of fluid jets released as the rotary jet head
performs its cleaning cycle. From the geared operation of the cleaning
device, and by receiving the impact force from the jets, the sensor
provides verification of satisfactory operation. The Rotacheck Sensor
System is self adjusted according to the tank pressure.
Cleaning Pattern
First cycle Full pattern
The above shows the cleaning pattern achieved by a Toftejorg rotary
jet head. Toftejorg Sanitary Rotacheck enables the user to confirm that
this operation has taken place on individual tank cleaning cycles.

Conditions Relating to the EX-Approval
The Universal Relay must be placed outside the hazardous area,
and the supply voltage for other kinds of equipment connected to
the same current circuit must not exceed Um = 250 VAC. When
installing the Sensor, please note that the electronics in the Sensor
are galvanically connected to the housing for EMC regulations, and
the Sensor must not be supplied from a source other than the
Universal Relay.
