A portable pig passage logger is a handheld reader that downloads passage records, with time and count, from EMT pig signalers in the field. It turns the detector’s on-board memory into a transferable, shareable log.

Introduction
A portable pig passage logger closes the loop on pig tracking. EMT’s signalers already record each pass with its time and store a campaign of events. The logger is the device that reads that memory at the site and moves it to a report, a phone or a control room. For crews without a laptop at the valve, it is the difference between a record you can use and a record you have to guess at.
What It Reads
The logger works with EMT signalers that keep a passage log, including the digital clock type that stores up to 99 passes with the trigger time, and the non-intrusive magnetic unit that logs the same data. It pulls the pass count and the time of each event so the handover shows exactly when the pig arrived at each station.
How It Connects
The signaler’s remote output is a passive contact rated 3A at 24V DC on a 1/2 NPT conduit, with power and signal leads separated. The logger taps that interface to read the stored records and, where the unit supports it, to clear the log after a successful transfer. EMT sets the connector to match the detector model.
Field Use
Carry it to each station, connect, and read the campaign in seconds. Because the data comes from the detector’s own memory, you avoid manual note-taking that drifts between shifts. The result is a clean record of pig arrivals across the line that you can file or forward.
Ordering Notes
Tell EMT which signaler models you run and whether you need the log cleared after read. The exact housing, battery and cable are confirmed per order so the reader matches your detector and your site.
Key Features
- Reads on-board log – Pulls pass count and time from the detector.
- Field handheld – No laptop needed at the valve.
- Clean handover – Replaces manual, drift-prone notes.
- Match to detector – Connector set to your signaler model.
- Transfer ready – Moves data to report, phone or control room.
- Clears log – Optional wipe after a good transfer.
FAQ
Which signalers does it read?
It reads EMT detectors that store a passage log, including the digital clock signaler that keeps 99 timed passes and the non-intrusive magnetic unit that logs the same data.
Do I still need a laptop at the pipe?
No. The logger reads the detector’s own memory in the field, which is the point. You collect a clean record without a computer at the valve.
Can it clear the detector log?
Where the signaler supports it, yes. Tell EMT at order so the reader is set to wipe the log after a good transfer.
