Vibration Monitoring & Machine Protection Systems
Transmitter Strategy
• Enable users to make use of their existing PLC and DCS
Systems for Machinery Condition Monitoring
• Offer Wonderware HMI systems where the users DCS or PLC is
inadequate or will be upgraded in the future

Transmitter Based Systems
•
Advantages:
•
•
•
•
•
•
•
•
•
•
Disadvantages:
•
www.stiweb.com
Low Cost (1/2 Legacy Systems)
Simple to Install
Can make use of existing sensors
Distributive Architecture
4-20 mA noise free
Digital to save wiring costs
Choice of Protocol
Easy repair and replacement
Local Dynamic Signal w/BNC
No Remote Dynamic or Transient Data
Vibration Monitoring & Machine Protection Systems
Legacy Systems
• Large centralized “Rack” based systems
•
•
•
•
•
•
Control Room mounted
Originally Capital Projects
OEM supplied sensors
All sensors wired to “Rack”
Requires lots of instrument wire and conduit (2x cost)
Large Racks do nothing that a PLC or DCS system cannot do
• Overall Values
• Time Delay
• Power up inhibit
• OK Circuit
• 99% not wired to “Shutdown”
• Many are ‘Obsolete”

Vibration Monitoring & Machine Protection Systems
What’s Changed ?
• Hardware
• PLC and DCS Systems are faster, cheaper and more common.
• Many Plants are upgrading to New DCS and PLC Systems.
• HMI Systems like Wonderware are available.
• People
•
•
•
•
•
•
•
•
Vibration and machinery specialists are retiring, or spread out.
A lot of specialty work is contracted.
Engineers and Technicians are forced to be “Jack of All Trades”.
Operators are being assigned more tasks “OCM”.
Users want smarter, simpler and easier to maintain systems.
Users are more budget conscious.
Engineers and Technicians are more computer oriented.
Major machine flaws have been fixed.

Vibration Monitoring & Machine Protection Systems
Distributive Systems
• Hard or Soft Alarms (Hardware or Software)
• Transmitters or Monitors are local to machine
• Analog to Digital Converters (ADC) new or existing
• Communications in users preferred protocol
• Modbus RS-485
• Modbus TCP/IP
• Hundreds of others
• Make use of existing networks
• Make use of existing Historians
• Keeps overhead and bandwidth requirement low
• Make use of Operators existing CRT’s !
• Instrumentation people understand 4-20 mA !
• No proprietary protocols
• Use all available hardware like Industrial Radio Modems
• Easy repair or replacement

Why 4-20 mA
•
•
•
Extremely accurate
Low voltages (typically 24 VDC)
Long distances can be handled
•
•
•
•
•
www.stiweb.com
Voltage has resistance losses
4-20 mA Current constant anywhere on loop
Noise immunity
Very common in process measurements
Instrument Technicians understand

4-20 mA Compliance
• Compliance – “The total amount of resistance in the circuit that
the 4-20 mA Transmitter is able to power”.
• Calculate by adding together:
• Shunt Resistor
• 100 Ω (.4 TO 2.00 Volts DC)
• 250 Ω (1 to 5 Volts DC)
• Wire Resistance (at 68° F)
• 18 AWG 6.385 Ω per 1,000’
• 20 AWG 10.15 Ω per 1,000’
• 22 AWG 16.14 Ω per 1,000’
• Power Protection Resistor (If used)

Ethernet TCP/IP
• TCP - Transmission Control Protocol, provides a reliable stream
delivery and virtual connection service to applications through
the use of sequenced acknowledgement with retransmission of
packets when necessary (TCP/IP).
• Ethernet - is a widely used data communications network
standard developed by DEC, Intel, and Xerox. It uses a bus
topology and CMSA/CD access method. The terms Ethernet
and the IEEE 802.3 standard are often used interchangeably.

•
•
•
•
•
•
•
•
