SURFACE PROFILE GAGES
-
Steel is often abrasive blast cleaned or otherwise roughened prior to painting. The peak-to-valley height of the resultant surface profile is an important factor in the performance of applied protective coatings. Low profile may reduce coating bond strength (adhesion). Too high and the peaks may receive insufficient coverage and possibly rust prematurely. The costly application of more coating may be required if the profile is too high. For these reasons, surface profile should be measured prior to coating application to ensure that it meets contract specifications.

Pressure Sensors
-
The output voltage changes with the absolute pressure applied to the pressure port. The gain, offset and thermal drift of the pressure sensor is digitally compensated to minimise errors and to create a single-ended, amplified output in the 0 to 5 Volt range.

Pressure Sensors
-
The output voltage of this sensor changes with absolute pressure. An internal amplifier creates a single-ended, amplified output in the 0 to 5 Volt range, so the sensor can be connected directly to most control units. The body and diaphragm are impervious to chemical attack by standard motorsport fluids.
