Storage Temperature

70°C (158oF) maximum. The probe should be stored with the plastic cover and desiccant packet threaded onto the probe. Store in a cool, dry environment.

Warm-up Time

Meets specified accuracy in 3 minutes

Accuracy

+/- 2°C from –65o to 40°C (-85o to 104oF)
+/- 3°C from –80o to –66°C (-112o to -87oF)

Repeatability

+/- 0.5°C from –65o to 40°C (-85o to 104oF) dew/frost point
+/- 1.0°C from –80o to –66°C (-112o to -87oF)

Response Time

Less than 5 seconds for 63% of a step change in moisture content in either wet-up or dry-down cycle

Electronics

Supply voltage

7 to 28 VDC (loop-powered, customer supplied)

Output

4 to 20 mA

Output Resolution

0.01 mA Max.

Loop R = 50 Ohms x (PSV–7), where PSV = Power Supply Voltage
Example: Given a 24 VDC Power Supply, Max. Loop R = 50 Ohms x (24–7) = 850 Ohms
