Transmitter: Analog, BTU,
Pulse and Protocol Output
DESCRIPTION
3x0 programmable transmitters are capable of converting the frequency signal from
any of our flow sensors to a preferred output type (analog, scaled pulse, protocol).
In addition to standard square wave signals, it can also accept a sine wave, making
it a versatile transmitter for numerous applications. The 310 and 320 offer analog
and scaled pulse output, respectively, while the 340 models offer communication
protocols (N2, BACnet/Modbus, or LonWorks), with energy (BTU) measurement
(appropriate software and programming cables are required for installation; see
Ordering Information).
APPLICATIONS
●
Converting sine/square wave signals to 4-20 mA and protocol
●
Increasing wire run length limit for flow sensors
●
Connecting flow sensors to BAS panels
FEATURES
●
Programmable (units of measure, calibration, etc.) using computer with
Windows™-based operating system...save installation time in the field by
pre-programming the device
●
Accepts sine wave input from a variety of other sources for application
flexibility
●
Compact size...saves space in crowded enclusures
●
Communication protocols available on the 340 models
