FAQs
Q1: What sensor is compatible with the 990 transmitter?
A1: It is designed for use with the 3300 NSv proximity probe and extension cable.
Q2: What is the power requirement for the unit?
A2: The unit operates from a 12–35 VDC power supply.
Q3: Can it be used in hazardous areas?
A3: Yes, it is certified for CSA Div 2 and ATEX Zone 0 and Zone 2.
Q4: What is the output signal type?
A4: A standard 4–20 mA loop-powered signal proportional to peak-to-peak vibration.
Q5: Is the output signal isolated?
A5: No, the dynamic output (“Prox Out”) is non-isolated; use a 122115-01 adapter for isolation.
Q6: How accurate is the transmitter?
A6: It maintains ±1.5% loop accuracy over the full-scale range.
Q7: What is the installation method?
A7: It supports DIN rail clips or bulkhead screw mounting.
Q8: What happens during a probe fault?
A8: The signal output drops below 3.6 mA, triggering a NOT OK condition.
Q9: Is there a diagnostic feature?
A9: Yes, “Prox Out” provides a diagnostic signal for test equipment.
Q10: Can it be used with grounded test instruments?
A10: Only with the 990/991 Test Adapter to isolate the “Prox Out” signal.
