  • Connection of voltage signals 0 – 10 V with characteristics that can be set individually
  • Monitoring of two independent values; the corresponding types of alarm can be set
  • Optical and acoustic alarms are emitted on the control panel
  • Power failure is displayed on the control panel
  • Monitoring parameters and additional functions can be adjusted using MConnect configuration software
  • For new installations and for refurbishment


Recording of the measured value to be monitored

  • Face velocity transducer VS-TRD
  • Differential pressure transducer with voltage signal
  • Volume flow rate transducer with voltage signal

Application

Application

  • Monitoring devices Type TFM-2-TPM for volume flow rates, face velocity or room differential pressure with optical and acoustic alarms and alarm signalling to higher-level systems (central BMS)
  • Selection of type of monitoring (volume flow rate, face velocity, differential pressure) with a single unit, configurable
  • Measuring with transducers (to be provided by others) that transform the measured value into an electric signal
  • For use in laboratories, clean rooms in the pharmaceutical and semiconductor industries, operation theatres, intensive care units
  • For new installations, retrofit, and refurbishment projects


TFM-2

  • Monitoring of the volume flow rate of fume cupboards, fume hoods, extraction arms to EN 1475; as an alternative, for the monitoring of volume flow rates in ducting

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
