Product Introduction
The Bently Nevada 1701/15 Field Monitor Proximitor Input Monitor is a precision monitoring device designed to measure proximity probe signals for machinery protection and diagnostic applications. It converts the proximity probe’s analog output into an accurately conditioned signal suitable for machinery monitoring systems. The unit provides high-resolution measurement and reliable output to ensure accurate and repeatable monitoring of shaft vibration, displacement, or position. Its robust design makes it suitable for installation in industrial environments with varying temperature and humidity conditions.
This monitor supports a range of input voltages and provides buffered output for integration with vibration monitoring systems. With fast read/write capabilities, precise gap resolution, and stable performance, it is ideal for critical rotating machinery where early detection of imbalance, misalignment, or bearing wear is essential.

FAQ
-
What is the maximum cable length for the buffered output without signal degradation?
Buffered output can reliably drive up to 30 m (100 ft) of 60pF/ft cable. -
Can the unit tolerate voltage fluctuations on the input power supply?
It is designed for -24 V and +5 V from the 1701 Power Supply. Minor deviations may be tolerated, but sustained voltage outside these limits is not recommended. -
What is the response time of the monitor for real-time measurements?
Flex read/write rate is ≥ 25 milliseconds between the monitor and the Flex adapter. -
How accurate is the gap measurement under typical operating conditions?
Gap accuracy is ±20 mV in the range -1 V to -23 V. -
Is the output electrically isolated?
No, the buffered output is not isolated; external isolation is required if needed. -
What is the resolution of the gap setpoint adjustment?
Gap setpoint resolution is 0.10 V. -
Can this monitor be used in high-humidity environments?
Yes, it operates safely in 5% to 95% non-condensing relative humidity. -
Does the monitor require additional calibration when connected to different transducers?
Standard calibration is suitable for most 1701 Proximitor probes; specific probe calibration may improve accuracy. -
What is the typical power consumption of the unit?
Power consumption is 1.5 W, not including the connected transducers. -
Can multiple 1701/15 monitors be used in parallel for complex machinery monitoring?
Yes, they can be connected to a shared monitoring system, but signal integrity and load considerations must be observed.
