SELECTING SUITABLE PRESSURE SENSOR
• To select a pressure sensor that can withstand a maximum of 12 bar(174 psi).
• Also to select a long-term stability, cost effective sensor with high accuracy, easy installation and low maintenance.
• Ceramic CAPACITIVE sensor is suitable for this purpose.

SELECTING SUITABLE SPEED SENSORMax. speed to be measured is
3900 rpm(revolutions per minute).
Preferred method - Contact type.
Size-should be compact.
Accordingly, FIXED TYPE DC TACHOMETER is suitable for this purpose.

SELECTING SUITABLE TEMPERATURE SENSOR
Max. temperature to be measured- 90 Degree Celsius.
Medium-water / Air.
It should have good reliability & low cost.
Accordingly, THERMOCOUPLE type temperature sensor is suitable for our purpose.
