Device description
The local display TD 8250 is a versatile on-site display for positive displacement flow sensors
by SIKA equipped with plug connection to DIN EN 175301-803-A.
The display is simply inserted between the plug and the plug
socket on the flow sensor.
The local display can be set to display flow or volume. For exter-
nal processing, two square wave signals shifted by 90° are avail-
able.
Flow sensors already supplied can be equipped with the local
display. For this purpose, the amplifier card must be removed
from the plug socket.
The local display is freely programmable. All necessary settings
can be made with two keys. The programmed data is stored on an
EEPROM and therefore saved in case of power failure.
As an option, the local display is available with an output which is
proportional to the flow rate (0…20 mA, 4…20 mA) or relay con-
tacts. The square wave signal is then not applicable.
The local display unit works with 24 VDC or 12 VDC.
Due to its characteristics, possibilities and low costs this instrument will be your first choice
especially for measuring of flow and volume.
1.1
Intended use
The local display TD 8250 may only be used to indicate flow rate and volume in conjunction
with the SIKA positive displacement flow sensors of the series VZ-S und VZ AL-S
