Model
1700
Digital Motor Temperature Monitor and Alarm System
Simultaneous readings from 6 sensors located
within the motor
Programmable Alarm Points
Help
prevent motor failure and expensive repairs
|
 |
|
The 1700 Systems are designed as safety instruments
for large motors (350 HP and larger). The Systems
monitor 6 customer set temperature points, either
RTD's or Thermocouples and provide an alarm for
overtemperature conditions. The system can be
configured to shut down the motors. With
modification the systems can monitor ground fault
and/or diode fault. Consideration is being given to
monitoring voltage and current.
The Model 1700 System scans multiple Resistance
Temperature Devices (RTD's) or Thermocouples
installed within the rotor windings or the starter
bars providing data on minute changes in thermal
condition of the motor. Reliable temperature
monitoring of the windings is key to smooth
operation. Overheating is a clear signal of an
impending problem.
This system monitors 6 rotor winding temperatures
simultaneously, displays all 6 rotor temperatures
simultaneously and will indicate any channel with a
temperature greater than a programmable alarm set
point. The alarm feature has a relay output. The
non-contact transmission method means no-fault path
from the rotor to ground exists. |

Module Support Ring -
1700A &
1705A: |
|
|
The module support ring
is an aluminum housing consisting of 2 pieces
forming a circle around the shaft. The housing adds
about 2.5 inches around the shaft. It is attached to
the shaft in a proprietary bolt pattern.
|
|
Module Support Ring -
1701A &
1706A: |
|
|
The module support ring
is a metal band clamp ("strap on collar") and a
counter balance assembly. The transmitter is
enclosed in a NEMA 4 enclosure, which is held by the
band clamp. These are secured to the shaft by
tightening T-bolt nuts to predefined torque levels.
|
|
Module Support Ring - 1702A: |
|
|
The module support ring
for the 1702 is attached by 4 bolts to a customer or
Sensotec Wireless Products provided adapter that is
installed in the shaft to be tested. The adapter is
a custom designed part and is not always possible.
The module support ring is a 2 piece arrangement
consisting of an aluminum transmitter housing inside
a fiberglass epoxy collar which holds the rotating
antenna. The size is approximately 8" diameter x 2"
width which results in a very light configuration.
|
|
Rotating Antenna: |
|
|
|
The rotating antenna for
the
1700A, 1702A and
1705A is a metal loop antenna that is assembled
in the module support ring. The rotating antenna for
1701A and 1706A is connected to the transmitter
housing cover and is held in place by a series of
supports to the module support ring. |

The
1211D PSU is a flange mounted box which contains
an impedance matching transformer and resonating
capacitance decade switch. This device matches the
high voltage low current 160 kHz oscillator power
source to the low voltage high current single loop
stationary antenna inserted into connections of the
1211D. In addition to transferring power to the
transmitter, the antenna also receives the RF data
signal and routes it via coaxial cable to the
receiver for processing.
The
1711A Power Module consists of a tunable power
amplifier (PTU) that is contained within a NEMA 12
enclosure and a stationary loop antenna that is
usually formed from 5/32 inch diameter brass rod.
The stationary antenna is placed around the
transmitter assembly and then connected to the PTU.
The PTU is secured by bracket to the motor housing.
The power module unit is powered by the receiver
electronics unit. In addition to transferring power
to the transmitter, the antenna also receives the RF
data signal and routes it via coaxial cable to the
receiver for processing. |
Model 1400
Digital Temperature Monitoring System |
Model 1700
Digital Motor Temperature Monitor and Alarm System |
 The
1400 digital temperature monitoring system is ideal for
use with large lime recovery, cement and alumina kilns
as well as industrial dryers and incinerators for
hazardous waste disposal. |
 The
1700 Systems are designed as safety instruments for
large motors (350 HP and larger). The Systems monitor 6
customer set temperature points, either RTD's or
Thermocouples and provide an alarm for over-temperature
conditions. |

Rotary Torque Measurement System |
|
 The
TMS 9000 torque measurement system represents an
advanced generation of rotary transformer sensors
designed to operate entirely in the digital domain for
enhanced accuracy and versatility. The TMS 9000 series
physically integrates rotor electronics and telemetry
into one element, with all set-up and output controlled
through computer software. |
