ETR-101A -- Exhaust Temperature Recording System


Model: Temperature Data Logger

Avaibility: AVAILABLE

Call For Price

The ETR101A is an Exhaust Temperature Profiling Kit designed to profile the exhaust temperature of on-road vehicles and off-road equipment, including tractor trailers, buses, trucks over 14,000 lbs., waste water vehicles, and sweepers. The ETR101A comes assembled and includes a data logger, temperature sensor (thermocouple type K), weatherproof enclosure, interface cable, hex screwdriver and software. A ¼” NPT coupler and a compression fitting is required for assembling, but not included.

Setup is fast and easy. The ¼” NPT coupler is attached to the exhaust pipe; the use of a compression fitting allows for the thermocouple to be placed directly in the exhaust stream, providing for highly accurate profiling. The data logger, which is contained within the weatherproof enclosure, is then mounted to the vehicle.

Using the MadgeTech software, the logger is programmed to record for a set period, generally three to five days. Data is stored in the data logger, and is downloadable at any time via a pc or laptop computer. The complete temperature profile is then provided to the diesel particulate filter (DPF) manufacturer, aiding in the selection of the correct DPF for the exhaust system.

Many DPF manufacturers, including Donaldson Corp., recommend the use of temperature profiling equipment, such as the MadgeTech ETR101A, to aid in the selection of the appropriate diesel particulate filter.

Wrap Around

Start Modes

• Immediate start

• Delay start up to 18 months

• Multiple pushbutton start/stop

Stop Modes

• Manual through software

• Timed (specific date and time)

Multiple Start/Stop Mode

Start and stop the device multiple times without having to download data or com-municate with a PC

Multiple Start/Stop Mode Activation

To start the device:

Press and hold the pushbutton for 5 seconds, the green LED will flash during this time. The device has started logging.

To stop the device:Press and hold the pushbutton for 5 seconds, the red LED will flash during this time. The device has stopped logging.

Real Time Recording

The device may be used with PC to monitor and record data in real-time

Alarm: Programmable high and low limits;

alarm is activated when temperature reaches or exceeds sets limits.

Alarm Delay: A cumulative alarm delay may be set in which the device will activate the alarm (via LED) only when the device has recorded a user specified time duration of data.

Trigger Setting

High and Low limits may be set for the thermocou

-ple channel. Once data meets or exceed sets limits,

the device will record to memory. Bi-level start and

stop triggers can also be programmed. Users can specify the number of readings to take after the device triggers

LED Funcionality

Green LED blinks:

10 second rate to indicate logging

15 second rate to indicate delay start mode

Red LED blinks:

10 second rate to indicate low battery and/or full memory

1 second rate to indicate an alarm condition

Password Protection

An optional password may be programmed into the device to restrict access to configuration options. Data may be read out without the password.
