Vibration monitoring TM1 CEMB

Main characteristics

Input vibration signals from velocity or acceleration transducer

Input signals from no-contact transducer or photocell (NPN) for phase or rotation measurements

Provision for installing low and/or high band-pass filters for selecting frequency of the input signals (nb: frequency of the low band-pass filter should be at least double that of the high band-pass filter)

Output signals of analog type proportional to the measured current signal (4 to 20 mA) or else voltage signal (0 to 10 Vdc) independent for each measuring channel

Digital output signals, presettable over the entire measurement range (for alarm and/or trip contacts of the machinery)

Digital output signal for self-diagnostics alarm with logic presettable by the user

Real time local display on digital readout of the value measured with selection by the user of the channel to be displayed.

Real time local display on LEDs regarding alarm status and self-diagnostics

Provision for interfacing with vibration analyzer (BNC)

Provision for interfacing with P.C. (RS 485)

Possibility of user operating on the alarm signals with regards to:

- time delay in tripping the alarm threshold

- alarm threshold multiplier

- relay impulse time

- type of relay operation (NR or NE)

- type of relay memorization

- relay inhibition when switching on

- relay operation bypass

- relay reset

- selection of mode of relay operation

Provision for varying the preset parameters by means of local push buttons (Fnn functions) or by P.C. via serial link RS485 (dedicated program)

Fixed on standardized DIN rail
