10-2 Height Sensor
Theory of Operation
The Height Sensor uses a 1.58 mm (0.0625 in) diameter stainless steel probe to contact the
dispensing surface. The probe tip is machined to a 0.51 mm (0.02 in) circle for minimum
surface contact. Approximately 5 grams (0.18 oz) of contact force is exerted during a
substrate height measurement. The low force eliminates substrate flex and vibration caused
by probing and reduces placement inaccuracy and damage to delicate substrates.
Using this substrate height information, the dispensing system maintains a constant
dispensing height during production runs.
Installation
Tools and Materials Needed

HS-RTA Height Sensor

Philips head screwdriver
Only a trained service technician should perform this procedure
Refer to Figure 10-2 to locate parts.
To install the HS-RTA Height Sensor:
1. Determine the type of valve or fluid pump installed on your dispensing system.
2. Align the Height Sensor to the screw holes on the right side of the valve bracket.
3. Use the Philips head screwdriver to secure the Height Sensor to the valve bracket
with the three screws included with the Height Sensor.

The top screw may not need to be used to secure the Height Sensor on some
valves.

DV-01, DV-02, DV-06 and DV-07 valves require the use of the
Bracket Spacer for installation of the Height Sensor (see Figure 10-2).
4. Plug the Height Sensor Power Cord into the Height Sensor connector on the back
of the dispensing head.
