Installation & Setup Guidance
Proper installation is essential for optimal performance. Follow these guidelines:
-
Mounting: The transducer can be mounted in any orientation. Use a stud mounting (3/8-in 24 to 1/2-in 20) for secure attachment. Ensure the mounting surface is clean and flat to achieve proper contact.
-
Torque: Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to avoid over-torquing, which can damage the housing or affect sensitivity.
-
Connector: The 2-pin MIL-C-5015 connector must be properly mated and locked to prevent signal loss. Use the specified cable (part number 02173006) for maximum signal integrity.
-
Cable Routing: Keep cable runs away from high-voltage lines and electromagnetic interference sources. The maximum cable length is 305 metres (1,000 ft.) with no signal degradation.
-
Polarity: Ensure correct wiring: Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer. Verify the output bias voltage (10.1 Vdc ± 1.0 Vdc) at the monitoring system.
Maintenance & Reliability
The 190501-02-00-01 is built for long-term reliability, but routine checks help ensure consistent performance:
-
Periodic Inspection: Inspect the mounting stud and connector for signs of loosening or corrosion. Re-torque if necessary within the specified range.
-
Cable Integrity: Check the cable for cuts, abrasion, or moisture ingress, especially in harsh environments. Replace if damaged.
-
Environmental Resistance: The 316L stainless steel case withstands corrosive atmospheres and can operate in 100% condensing humidity (non-submerged).
-
Shock and Vibration: The transducer handles shock up to 5000 g pk, making it resilient to transient impacts.
Regular maintenance minimizes the risk of false readings and extends the service life of the transducer, contributing to lower total cost of ownership.
