TEHAG - Model PTL -Filter Monitoring Systems
The PTL filter monitoring is especially developed for constant function monitoring of diesel particulate filter systems. The electronical device measures the exhaust temperature as well as the back pressure ahead of the filter. To suit each vehicle type and effort, additional a measuring probe for recording the number of revolutions can be connected. By the default option the displaying of the operating states take place via a three-tone LED, which is installed in the cockpit of the vehicle or rather engine. Possible malfunctions as well as the load status of the particulate filter are able to be recognized immediately and can be eliminated by the driver if necessary.
- Connection to the On-board system: 12–35 V DC
- Measurement range PRESSURE/TEMPERATURE: 0–400 mbar / 0–800 °C
- Measurement interval / memory interval default: 1 second / 10 seconds
- Alarm value setting: Programmable via software
- Memory module/Data logger: Circular, non-volatile memory as well as non deleteable alarm value memory
- Memory capacity: 1 Mio. data records (date/time/temperature/pressure readout)
- Record start: Exhaust temperature > 100 °C or revs signal
According to customer requests, the PTL filter monitoring is able to be equipped with further display screens. Under "Options" below, you can find closer details. As standard feature the device is equipped with an memory module which records all measured operating data (temperature, back pressure, revs, alarm indicator) in freely selectable intervals. The whole electronic is built-in an IP 65, aluminium die-cast housing, and therefore suitable for an assembly in the engine compartment or external undeveloped land.
- Digital device for clearly display temperature and backpressure (On and offroad variation)
- Acoustic signal
- Automatic switching off in case of overrange the prepared alarm value
- Elektronic control for increasing the exhaust temperature (dependent on application)
- Data cable and software „Service Program PTL“ for readout the memory and to program the system
- Data remote access via mobilphone or PC
