CAUTION
Sensor/Process Application Compatibility
The wetted sensor materials may not be compatible with process composition and operating conditions.
Application compatibility is entirely the responsibility of the user.
CAUTION
The 402 and 402VP sensors are retractable. BEFORE RETRACTING THE SENSOR, be absolutely certain the process pressure
is less than 64 psig (542 kPa abs) and the process temperature is at a safe level!
