Model 1400
Digital Temperature Monitoring System
Save Energy

Structure From Damage
|
 |
| 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. It is designed to provide
internal temperature data that can be vital in a variety of applications.
The 1400 features
a digital transmitter mounted on the exterior of the rotating surface
to constantly monitor and transmit data from thermocouples mounted
inside the kiln. The system uses inductive power so that temperatures
can be obtained continuously from rotating equipment without the use
of wires or batteries. |

The
Model 1420A Power Module Assembly consists
of a tunable power amplifier that is mounted in an enclosure. The
enclosure is mounted on a frame that contains a multicoil winding
that is used to provide operating power to the transmitter. The winding
acts as the primary of an air core transformer operating at 160 kHz
and the rotating antenna is the secondary. The frame is mounted in-line
with the rotating antenna on a radial from the center of the kiln.
Power to drive the coil is provided by the receiver. |

The
Model 1427A Rotating Antenna Assembly
consists of a stainless-steel strap structure which supports a brass
antenna approximately six inches from the outer shell. The antenna
is assembled using pairs of stainless-steel springs to join sections.
The springs maintain tension as the shell expands and contracts during
periods of warm-up and cooling. |
| Stationary
Antenna: |
|
| |
The
Model 1408A Stationary Antenna Assembly
consists of a segmented wip antenna and tuning assembly that receives
the data signal from the transmitter and routes this signal via a
coaxial cable to the receiver. The Model 1401B is generally not used
on full size kilns and requires substantially more user involvement
to set up. However, in unique situations it is available. The 1401B
system consists of the following: |

The 1418BU
Transmitter has the same specifications as the 1418B.
The differences are in the size and construction. The 1442B
Receiver is the same as is used in the 1400B.
The 1411B PTU consists
of impedance matching circuits and switch adjustable capacitors
which are mounted on a stationary enclosure near the stationary
antenna. The unit receives power from the receiver by cable and
provides the induction power to the transmitter via the antennas.
The antenna arrangement
is unique to each project. |
