|
Lectrotek’s range
of Temperature and Process Scanners, Data
Loggers and Data Acquisition Systems are used
for monitoring of critical equipment for their
healthy condition, safety, interlocking and
provide alarm & trip relays in case of fault
conditions such as exceeding/falling below set
values, or open sensor conditions etc. |
|
| |
|
|
|
 |
Application: Lectrotek
Scanners are used for monitoring equipment such as
HT motors, alternators, diesel engines, turbines,
boilers, HVAC systems etc. |
|
|
Versions: solid-state (Model 881) and
microprocessor-based (Uniscan-series) |
|
|
Universal inputs: programmable inputs for every
channels – RTDs, thermocouples, 4-20mA DC etc. |
|
|
|
|
Features: choice of alarm/trip output relays,
Modbus communication, retransmission of maximum
value |
|
|
Packaging in enclosures suitable for various
panel cutouts, rack-mount versions, field and
flameproof versions etc. |
|
|
Comparative features are provided, along with
downloadable data sheets. |

TEMPERATURE /
PROCESS SCANNERS |
 |
| |
|
Temperature /
Process Scanner Series (UniScan–NX / H / V &
UniScan-144) are Universal Input Scanner
intended for continuous monitors of process
parameters.
It incorporates advanced software features and
micro controller based design to provide
complete user flexibility and can cater to
almost all monitoring and data acquisition needs
of the user. It can be user programmed to cover
different application needs thus reducing time,
inventory and spares cost. It accepts direct
signals from thermocouples, RTDs and linear
voltage and current inputs, either as fixed type
or programmable universal input. Each channel is
sequentially scanned and active channels are
displayed, Individual channels can be locked for
monitoring using the E key. Flexible alarm logic
and grouping is provided to energize alarm relay
outputs as per the process parameter values and
programmed set points.
Serial communication is provided to enable the
scanner to communicate with PC (RS 232/RS 485
optional). |
