Powered pH / ORP / Ion Sensor Amplifier |
| TRA-IS1-B1a
(See
Fig.1) |
Input:
pH-,
ORP-, Ion-Selective Electrode via BNC Connector.
Output:
Voltage Signal via BNC Connector (Refer to Transfer Function below).
Power Supply:
For Transfer Functions with an output range up to ±3000 mV
and 4 Li-Mn batteries, CR 2032 will power the unit for 3 years.
Number
of Channels: 1 Channel (Electrode)
Isolation:
Input Ground directly connected to Output Ground.
If Galvanic Isolation is required it has to be provided on the receiving
side.
Enclosure:
Cream colour ABS, dimensions: 100 x 68 x 50 mm with two 15 mm
flanges (the flanges have four 5.5 mm fixing holes), IP 65 / NEMA
4.
Transfer Function:
Variant a: 1 to 1 Input to Output transfer.
Variant
b:
1 to 5 Input to Output transfer, which gives higher accuracy and
noise-immunity for Ion-selective measurements. |
