Vibration monitoring system DTM10

conditionpowerspeed

The DTM10 distributed vibration transmitter-monitor is ideal for monitoring machine vibration using proximity probes and a Modbus interface to a PLC or DCS system. The DTM also contains redundant power supplies and redundant 4-20mA transmissions. Using PVTVM’s unique strategy, the DTM can interface with almost any proximity probe system without hardware changes. Electrical Power Supply: 22-30VDC, 150mA. Galvanic isolation Frequency Response (-3dB): Nominal frequency: 4 ~ 3.0KHz Low frequency: 0.5 ~ 100Hz Proximity probe Interface: Sensitivity: 5mm and 8mm probe: 8 mV/um (200 mv/mil) 11mm probe: 4 mv/um (100 mv/mil) 25mm probe: 2mv/um (50 mv/mil) Buffered Output: Original, un-filtered signal Impedance: 150Ω Maximum cable distance: 300m (1000ft) Sensitivity: same as the sensor Local BNC connection and terminal block S0 and S1 options: Source, Non isolated S2 and S3 options: Passive, Galvanic isolation, 1000VDC Power supply range: 22-30VDC 4-20mA Output: Dual 4-20mA, sourced (loop power not required) Maximum load resistance: 380Ω Alarm Setup: 0 ~ 100% FS. Accuracy: ±0.1%. Delay: 1~60s, according to 1 second increase, default is 3s. Speed monitor without delay. Relays: Seal: Epoxy Capacity: 0.2A/240VAC, 0.4A/110VAC or 2.0A/24VDC, resistive load Relay type: SPTD Isolation: 1000VDC LED Machine Condition Indicator: OK: System OK indication ALT: Vibration over ALERT level DNG: Vibration over DANGER level BYP: System in BYPASS
