The Data Industrial Series 340 Btu transmitter is an economical, compact device for sub-metering
applications.
The 340 calculates thermal energy by measuring liquid flow in a closed pipe system and measuring
temperature at inlet and outlet points. The 340 requires two 10 kΩ thermistors for temperature input.
The flow input may be provided by any Data Industrial sensor and many other pulse or sine wave signal
flow sensors.
The onboard microcontroller and digital circuitry make precise measurements and produce accurate
drift-free outputs. The 340 is programmed using Data Industrial's Windows
Industrial A301 programming cable. Calibration information for the flow sensor, units of measurement
and output scaling may be downloaded prior to installation or in the field. While the unit is connected to
a PC or laptop computer, real-time flow rate, flow total, both temperature readings, energy rate and
energy total are available.
The Series 340 transmitter features two LED's to verify input and output signals.
The standard output for the Series 340 is an isolated solid state switch closure that is user programmed
for units of energy or flow. The output pulse width is adjustable from 50 mS to 5 sec.
The Series 340 Btu transmitter operates on AC or DC power supplies ranging from 12 to 24 volts.
The compact cast epoxy body measures 3.65"(93mm) x 2.95"(75mm) and can be easily mounted on
panels, DIN rails or enclosures.
