2-Wire Head And Railmount Transmitters
If you need a high accuracy 2-wire transmitter at a price you can live
with, these advanced, easy-to-use transmitters are available in three
different models and accept MilliVolt, POOO, and Thermocouple (Types J, K,
and T) inputs. They offer ±O.1% accuracies at some of the lowest prices in
the industry.
The BMN-53 is a fully-scalable head-mount transmitter that is
fully-adjustable (via solderlink and precision 20-turn. potentiometers) from
OºC/OºF to the full limit of the sensor.
The BMN-57 is a factory-scaled, fixed-range transmitter with a unique
difference: it is field scalable up to 100% of the factory-set range. (i.e.
a 0º to 100ºC unit can be field-scaled anywhere between 0º to 100ºC/0º
to 200ºF, 0º to 200ºC/0º to 400ºF). The Zero is also adjustable from
-25º to +25ºC/-10 to 70ºF.
The BMN-49 is a fully-scalable rail-mount transmitter that offers maximum
flexibility. It also offers you the capability to shift the Zero point so
your range doesn't have to start at OºC/OºF. (For RTDs you can shift the
Zero between -50º and 350ºC/-50ºC and 650ºF. For Thermocouples you can
shift the Zero between -50º and 400ºC/OºC and 750ºF.)
What is a Transmitter?
Basically, a transmitter is a signal conditioner. It accepts a low level
signal from a sensor, a millivolt signal from a thermocouple or a resistance
signal from an RTD (Pt100), and provides an output signal that is directly
proportional to the input-signal. Most transmitters provide a current output
signal (generally 4-20 mA or 0-20 mA signal) rather than a voltage output.
Conversion to a current signal virtually eliminates any interference from
line noise and allows accurate tranmission over relatively long distances
using ordinary uncompensated copper wire. The use of expensive thermocouple
wire or extension wire is no longer necessary.
Transmitters are available in both isolated and non-isolated versions.
Isolated transmitters are used to provide galvanic separation between the
sensor input and signal output. When grounded sensors are used or leakage to
ground occurs (with ungrounded thermocouples), isolated transmitters must be
used.
