Product Introduction

technical parameter
Sensor input: Two independent electric speed sensor inputs, such as EPRO's PR9266/... and PR9268/... series; Maximum allowable input voltage ± 10V; Input impedance>100K Ω.
Measurement range: The vibration velocity range of 0... 5/10/25/50/100mm/s can be selected by toggling the switch, depending on the input sensitivity of 30/28.5/22mV/mm/s; Or choose a range of 0... 25/50/100/125/250/500 μ m amplitude (0-P), with a sensitivity of 30/28.5/22mV/mm/s.
Frequency range: 5/10... 1000Hz (DIN45670).
Linear error:< 0.25%.
Temperature drift: Zero point<0.05%/K, gain range<0.01%/K.
Time drift: Zero point<0.01%/24 hours, gain range<0.01%/24 hours.

Measurement signal output
Two 0/4... 20mA current outputs, one for each channel, proportional to the corresponding input, or one current output proportional to max (Sxpp, Sypp), Smax, allowing a load of 500 Ω, with short-circuit and open circuit protection.
Two buffered voltage outputs (2-10V), one for each channel, proportional to the input dynamic signal, used for testing, analysis, and diagnosis.
One "OK" status output and two limit value outputs.
Power supply: 18... 24... 31.2V DC, the transmitter circuit is electrically isolated from the power supply through a DC/DC converter.
Current consumption: approximately 100mA/24V.
Power consumption: approximately 2.5 watts.

Allowable vibration and impact: 20g/2ms impact, 5g at 60Hz vibration.
Dimensions: 127.5mm x 125.75mm x 80mm (width x height x thickness).
Weight: Net weight is about 1300 grams, gross weight is about 1500 grams.

Functional Features
Dual channel design: can simultaneously monitor the vibration of two bearings, improving monitoring efficiency and accuracy.
Signal conversion function: It can convert the sensor input signal into an output proportional to the vibration velocity or displacement peak value, which is convenient for subsequent measurement and analysis.
Self check function: Built in "self check" circuit can monitor sensor and transmitter circuit faults. When a fault is detected, the logic "OK" output changes state, and the current output changes from 4-20mA to 0mA.
Limit detection function: When using dual channels, the characteristic value of channel 1 is monitored by a yellow alarm light, and the characteristic value of channel 2 is monitored by a red alarm light; In single channel mode, the limit can be set.
Compliant with standards: Compliant with general standards such as VDI2056.
Redundant power supply: There are two redundant 24V DC power inputs to improve system reliability.

application area 
Suitable for various types of turbomachinery, including but not limited to large and small steam turbines, fans, blowers, compressors, gearboxes, centrifuges, pumps, coal mills, etc. It is not only suitable for large equipment in power plants, refineries, and chemical plants, but also for independent monitoring of small turbomachinery with few measurement points.
