TECHNICAL PROFILE
Measurement & Construction
|
INSTALLATION GEOMETRY
Stable casing measurement
Mounting torque: 4.5 N·m ±0.6 N·m

APPLICATION LOGIC
Why the CT configuration matters
The 190501 family is specifically tuned toward lower-frequency velocity measurement. Its frequency response extends downward to 1.5 Hz at the ±3 dB specification, supporting fan assemblies that can run at relatively low rotational speeds.
Typical target equipment includes cooling tower and air-cooled heat-exchanger fan assemblies operating at or above 90 rpm.
|
VELOMITOR FAMILY / SYSTEM RELATION
190501 vs. related velocity sensing options
The 190501 should therefore be selected around the required low-frequency response and the actual machine mounting location rather than treated as a generic substitute for every velocity sensor.

BUYING & APPLICATION QUESTIONS
190501-12-00-01 FAQ
|
|
|
Q1 · Is 190501-12-00-01 intended for low-speed fan machinery?
Yes. The 190501 Velomitor CT was designed specifically for casing vibration velocity measurement on cooling tower and air-cooled heat-exchanger fan assemblies operating at or above 90 rpm, with 100–300 rpm described as typical operating speed.
|
Q2 · What does 190501-12-00-01 provide that matters for low-frequency vibration?
Its specified frequency response reaches 1.5 Hz to 1.0 kHz at ±3.0 dB and 3.0 Hz to 900 Hz at ±1.0 dB. This lower-frequency response is the key characteristic when monitoring slower rotating fan assemblies.
|
|
Q3 · Can 190501-12-00-01 be used with a long cable run?
The specified maximum cable length is 305 m (1,000 ft) when using the specified 02173006 cable, with no signal degradation under the stated conditions. The datasheet also gives 219 m (720 ft) as a recommended cable length under a defined vibration, frequency and cable-capacitance condition.
|
Q4 · What should be checked when installing 190501-12-00-01 on a machine casing?
The transducer should be installed on an appropriate bearing housing or machine casing where the machine vibration is effectively transmitted. For the specified configuration, the mounting surface is 33 mm in diameter and the mounting torque is 4.5 N·m ±0.6 N·m. Poor installation can reduce amplitude or frequency response or create signals that do not represent actual vibration.
|
|
Q5 · What does the 190501-12-00-01 suffix configuration mean when ordering a replacement?
The ordering code is structured as 190501-AA-BB-CC. For this exact part number, -12 specifies the plate stud mounting option, 3/8-in 24 to M8x1; -00 specifies the MIL-C-5015 connection interface; and -01 specifies the agency approval option within the multiple-approval group. Matching these three configuration fields is important when replacing an installed unit.

The 3500/22M 138607-01 Transient Data Interface (TDI) is the interface between the 3500 monitoring system and compatible software (System 1 Condition Monitoring and Diagnostic software and 3500 System Configuration software). The TDI combines the function of a 3500/20 Rack Interface Module (RIM) with the data collection capability of a communication processor such as TDXnet.
3500/22M is a Transient Data Interface Module manufactured and designed by Bently Nevada as part of the 3500 Series used for monitoring seismic activity.

The 3500/33 16-Channel Relay Module is a full-height module that provides 16 relay outputs. You can place any number of 16-channel relay modules in any of the slots to the right of the Transient Data Interface (TDI) Module. Each output of the 3500/33 16-Channel Relay Module can be independently programmed to perform voting logic.
The 3500/60 & 61 modules provide six channels of temperature monitoring and accept both Resistance Temperature Detector (RTD) and Thermocouple (TC) temperature inputs. The modules condition these inputs and compare them against user-programmable alarm setpoints. The 3500/60 and 3500/61 provide identical functionality except that the 3500/61 provides recorder outputs for each of its six channels while the 3500/60 does not.

The 3500/72M Recip Rod Position Monitor meets API 618 requirements for reciprocating compressors. It measures: l Rod position l Rod drop l Hyper-compressor The four-channel 3500/72M Recip Rod Position Monitor accepts input from proximity transducers, conditions the signal to provide dynamic and static position measurements, and compares the conditioned signals with userprogrammable alarms. Each channel, depending on how you configure it, typically conditions its input signal to generate various parameters called measured values.
The 3500/62 Process Variable Monitor is a 6-channel monitor for processing machine critical parameters that merit continuous monitoring, such as pressures, flows, temperatures, and levels. The monitor accepts +4 to +20 mA current inputs or any proportional voltage inputs between -10 Vdc and +10 Vdc. It conditions these signals and compares the conditioned signals to user-programmable alarm setpoints.
