162 VTS 2-WIRE SEISMIC VIBRATION TRANSMITTER
Installation Manual
Doc# M9450 • REV G (October 2016)
OVERVIEW
The 162VTS vibration transmitter is ideal for
sensing vibration on most plant equipment.
It generates a two-wire loop signal propor-
tional to velocity for transfer to a program-
mable logic controller (PLC), distributed
control system (DCS) or other 4-20 mA input
devices. Simply mount the transmitter on
the machine case, connect the 2-wire loop
and read and/or record the vibration.
FEATURES
• Provides 4-20 mA signal proportional to
velocity vibration
• Direct connection to PLC, DCS or other
recording monitor
• Two wire, loop powered, simplifies field
wiring, IPT™ reversible power
• Different top wiring configurations and
mounting stud types
IPT™ (Independent Polarity Terminal) is a
registered trademark of Metrix Instrument Co.

- Page 2 The Model 162VTS Seismic Vibration Transmitter is part of an established series of transmit- ters from Metrix. The device incorporates state-of-the-art electronic components and circuits. It also offers several new options in terms of features and configurations. Study the configuration of the transmitter before putting it in service.
- Page 3 A minimum of five (5) threads of engagement should be made. A 1/4 inch to 1/2 inch NPT bushing is available for mounting the transmitter in existing 1/2 inch NPT holes. Also, a Metrix 7084 Flange Adapter can be used between the transmitter and the machine Figure 1 surface when there is not enough surface thickness to drill and tap a hole.
- Page 4 1. SAFE AREA INSTALLATION: Connect the field wiring in accordance with the appropriate dia- gram shown in Figure 3. The 162VTS transmitter requires a minimum of 11 VDC for proper operation. The minimum loop power supply voltage required is 11 VDC plus 1 volt for each 50 W of loop resistance.
- Page 5 2. EXPLOSION-PROOF INSTALLATION IN HAZARDOUS LOCATIONS 162VTS transmitters are CSA certified explosion-proof, Class I (B, C & D); Class II (E, F & G,). Connect the field wiring in accordance with the appropriate diagram shown in Figure 3. Refer to “Safe Area Installation” paragraph on Page 4 for loop voltage and resistance require- ments.
- Page 6 A 2- to 3-second delay is normally applied to most machinery. Consult Metrix if you have a question about your machines operating characteristics.
- Page 7 CALIBRATION The 162VTS transmitter has been factory calibrated for the full scale vibration level marked on the label (see datasheet Doc#1004597 Option “A”). If the calibration is in doubt the unit can be verified in the field by following the procedures outlined below. Note that there are no Zero and Span adjustments on the transmitter.
