Digital
transmitters produce signals that exist
only in one of two states: ON or OFF.
These states may also be referred to as
HIGH or LOW, or 1 or 0 (zero).
Model
VR7697 (Models 35, 43 & 45)
This economical
and versatile bi-directional digital pulse
transmitter provides 10 pulses per revolution
with excitation power of 115-250 VAC or
12-36 VDC, making it compatible with most
remote read-out equipment. Used with 600
Series Register.
Model
VR7671 (HR) (Models 35 HR, 43 HR, &
45 HR)
This solid
state Hall Effect digital pulse transmitter
provides 100 pulses per revolution. Note
that input (excitation) power is limited
to 10-15 VDC.
Model
PE 500
This Solid
State Optical transmitter provides 100
pulses per revolution to a frequency of
2000 Hz. These units are bi-directional,
and are CURRENT SOURCING. Current Sourcing
means a sensor supplies the voltage to
the count input. Sourcing sensors are
PNP transistor outputs or a contact closure
to V+.
Model
PE 505
The Model
505 is the same as Model 500, with the
exception that it is CURRENT SINKING and
is compatible with TTL circuits. Current
Sinking means a sensor provides a path
to DC common for the count input. Sinking
sensors are NPN transistor outputs or
a contact closure to DC common.
Model
PES 550
The Model
550 is the same as the 500 with the addition
of an internal pulse-scaling module with
a selectable scale range (multiplier)
of 0.0001 to 1.9999. The output pulse
may be adjusted to correct for flowmeter
wear, compensate for a nonstandard liquid
viscosity, or to convert from one engineering
unit to another. The Model 550 is current
sourcing.
Model
PES 555
This model
is the same as Model 550 with the exception
that it is Current Sinking
