Product Description
Technical data
1. Sensor requirements:
Magnetoresistive sensor: single or dual TTL level signal output; Active type, output TTL level signal with the proportion of speed and frequency; Installation clearance: 2mm±0.5mm.
Eddy current sensor: sensitivity: 7.87 mV/μm (200 mV/mil), GAP voltage: -10VDC.
Note: The installation clearance is determined by the mechanical distance of 1mm between the tooth top and the probe or the output voltage of the preamplifier -10VDC, and the mechanical distance is given priority to avoid damage to the probe caused by the eccentricity of the rotating shaft.
2. Measuring range:
Range: 0~9999rpm Accuracy: ±0.5%±1 rpm
Note: The range can be programmed on site.
3. Power supply:
DC power supply: 24VDC (18~36V);
AC power supply: 220VAC(165~260)/47~63Hz;
AC power supply: 110VAC /47~63Hz;
Power consumption: 5W.
4. Standard signal output:
Standard current: 4~20mA (corresponding to the upper limit of full scale)
Active: Drive load: ≤500Ω, effective transmission distance: ≤ 300 m (1000 ft).
5. Relay output:
Two-stage threshold (Alert, R-Alert) programmable setting and normally open and closed dry contact output, the full scale range can be set, and the error is ≤0.1%;
Insulation resistance: ≥1000MΩ;
Contact capacity: 2A/30VDC, Double Pole Double Throw (DPDT);
Alarm delay: 0.1 to 60S, default value: 0.5S;
Alarm Latching: The default is non-latching.
6. Physical characteristics:
