Signal Function and System Interface
The 4-20 mA output provides a standard analog signal for compatible control or monitoring inputs. The receiving system must interpret the current against the transmitter’s configured measurement range. Confirm the scaling, loop wiring, load resistance and fault-current behavior before commissioning, as the available information does not establish these details for the complete order code.
Frequently Asked Questions
Q: What does the Bently Nevada 1800/20-12-90-02-00 measure?
A: The supplied product descriptions identify it as a thrust position transmitter for axial displacement monitoring. Confirm the applicable probe arrangement and measurement configuration before replacing an existing unit.
Q: Can this transmitter connect to a PLC or DCS?
A: The listed 4-20 mA output is suitable in principle for a compatible analog input. Verify the electrical interface, loop power requirements, load limits and signal scaling before connecting it to the receiving system.
Q: Which operating temperature range should be used for selection?
A: The supplied descriptions conflict: one states -40 to +85 deg C, while another states -20 to +70 deg C. Confirm the correct environmental rating for this exact model before installation.
