Functional description

The TFM-2/TPM monitoring device enables monitoring of the aerodynamic function of fume cupboards as well as monitoring spaces where the differential pressure is being controlled.

The measuring variable (volume flow rate, face velocity or pressure) is recorded by an external transducer (to be provided by others). The transducer provides a voltage signal that is proportional to the variable; the signal is then transmitted to the monitoring device and evaluated by the microprocessor system.

The characteristics for the transducer, the monitoring settings and any required special functions can be configured with the free-of-charge TROX MConnect software.

Optical and acoustic alarms are emitted on the supplied control panel. Alarm signalling to the central BMS can be achieved by wiring the alarm relay. Failure of the supply voltage is also signalled to the control panel.

The following parameters and functions can be set:

  • Type of monitoring: Volume flow rate, face velocity or differential pressure
  • Characteristic of the transducer
  • Monitoring of 2 independent values, with individual types of alarms if the actual values deviate from the set limits
  • Switching (switch contact) between the two values being monitored
  • Monitoring can be switched off (switch contact), e.g. for night-time operation
  • Control panel button to switch lighting on/off

Configuration settings are stored in EEPROM memory and are hence safe in case of a power failure.

Monitoring devices for the monitoring of volume flow rate, room pressure, or face velocity on a fume cupboard. The quantity being monitored is received as a 0 – 10 V DC voltage signal from external transducers, e.g. face velocity transducer or volume flow measuring unit.

The monitoring system includes a microprocessor in a casing, a control panel (also for display), a sticker to mark the control panel for either volume flow rate and face velocity monitoring or for room pressure monitoring.

Special characteristics

  • Monitoring of volume flow rate, differential pressure or face velocity
  • Measurement recording with transducer (to be provided by others) as 0 – 10 V signal
  • Two values can be monitored, switching between the two is possible; alarms can be configured; monitoring can be switched off
  • Optical and acoustic alarms are emitted on the control panel
  • Signalling of normal operation, measured value higher or lower than setpoint, power failure
  • Conventional alarm signalling (switch contact) to the central BMS
  • On-site configuration with free-of-charge configuration software MConnect
