Performance and Durability

The 330191-00-16-15-05 operates with a supply voltage of -17.5 Vdc to -26 Vdc when connected to a nonincendive circuit per installation drawing 140979, with a maximum current consumption of 12 mA. When used with barriers, the range is -23 Vdc to -26 Vdc. The output resistance is 50 Ω, and the sensitivity variation is less than 2 mV per volt change in input voltage.

This probe features patented TipLoc and CableLoc designs, providing a robust bond between the probe tip and body, and a pull strength of 330 N (75 lbf) to secure the cable. The 8 mm probe design offers a thicker encapsulation of the probe coil in molded PPS plastic, making it more rugged against physical abuse. The larger diameter of the probe body contributes to a stronger, more robust case.

Industry Applications

The 330191-00-16-15-05 is ideal for vibration monitoring on turbomachinery, compressors, pumps, and electric motors. Its 8 mm probe size and 3/8-24 UNF thread allow for easy installation in standard mounting holes. The 1.5-meter cable length is suitable for close-coupled installations where the probe connects directly to a proximitor or extension cable.

With CSA, ATEX, and IECEx approvals, this probe is certified for use in potentially explosive atmospheres, making it a dependable choice for oil & gas, chemical, and power generation facilities. The optional FluidLoc cable option prevents oil and other liquids from leaking out of the machine through the cable interior, enhancing reliability in wet environments.

Installation and Setup

When installing the 330191-00-16-15-05, ensure the mounting hole is clean and free of debris. Apply the recommended torque of 0.565 N•m (5 in•lbf) to the connector to avoid damage. The probe case thread engagement should not exceed 0.563 inches to prevent interference with the sensing tip. For systems using extension cables, verify that the total cable length matches the system requirements (e.g., 1.5 meters). One-meter systems do not use an extension cable.

Calibrate the probe according to the manufacturer's guidelines to ensure accurate gap voltage readings. The probe requires a supply voltage within the specified range to maintain linear output. Operation at a more positive voltage than -23.5 Vdc may reduce the linear range.

Maintenance and Reliability

The 330191-00-16-15-05 is designed for long-term reliability with minimal maintenance. The stainless steel case and PPS tip resist corrosion and wear. The cable's 330 N (75 lbf) pull strength reduces the risk of connector damage. For safety-rated applications, follow the manufacturer's safety manual for periodic inspection and testing. Avoid disassembly or internal repairs; contact BluePLC Industrial for replacement units if needed.

Environmental temperature limits vary by temperature classification (T1 to T5), ranging from -55°C to +232°C for the probe only. Ensure the operating environment stays within the specified range for the chosen temperature class.

Selection and Purchasing Advice

Before ordering, confirm the required total probe length, thread type, and armor option. The 330191-00-16-15-05 is a non-armored version with a 1.5-meter cable. If you need a different length or armored cable, other part numbers are available. BluePLC Industrial offers this probe as new and original with a 12-month warranty.
