1.
Description.
The
WSD12-EVTT
is a
datalogger
with 2 clean contact or “open collector” inputs capable to count pulses coming from a thermal
energy meter (
energy and volume
).
Channels 3 and 4 are equipped with contact NTC10K
Ω
BETA 3435 temperature sensors to acquire the heat-transfer fluid temperature
(
flow and return
).
All channels are provided with storage functionality of samples acquired.
2.
Configuration.
It is necessary to verify the setup regarding the weight expressed in Wh and litres matching the impulse supplied from the energy
meter to which the
