Electrical Performance
This probe operates with a power supply ranging from -17.5 Vdc to -26 Vdc, with a maximum consumption of 12 mA. It offers a supply sensitivity of less than 2 mV change in output voltage per volt change in input voltage, ensuring stable readings. The output resistance is 50 W, and the probe's DC resistance is 7.59 Ω ± 0.50 Ω for a 1.0-meter length.
Mechanical and Environmental Durability
Engineered for harsh industrial conditions, the 330171-00-20-10-02-00 features a probe case made of AISI 303 or 304 stainless steel, providing excellent corrosion resistance. The probe cable is a 75 Ω triaxial, fluoroethylene propylene (FEP) insulated cable, available in lengths of 0.5, 1, 2, 5, or 9 meters. The probe can withstand temperatures from -35°C to +177°C (-31°F to +351°F), making it suitable for a wide range of operating environments.
Installation Guidance
For optimal performance, mount the probe with a recommended torque of 5.1 N·m (45 in·lb), and do not exceed 7.3 N·m (65 in·lb). The maximum thread engagement length is 0.375 inches. When drilling and tapping a mounting hole for the 1/4-28 thread, use a #3 or larger tap drill to ensure proper fit and alignment. Maintain a minimum cable bend radius of 25.4 mm (1.0 inch) to prevent damage.
Maintenance and Reliability
Regular inspection of the probe and cable connections is essential to maintain measurement accuracy. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The probe's tensile strength of 222 N (50 lbf) ensures robust mechanical integrity, reducing the risk of failure in high-vibration applications.
