EMS-LD-P1
Controller-powered, no relays.
Point probes · 5 codes
Point leak probes for liquid cooling
One probe covers one monitored point and reports that point.
Height
0–4.8mm above the surface
Adjustable.
Leader
4.3m (14 ft) as standard
Rack probe: 2.0 m uplink.
Body 39.4 × 50.8 × 25.4 mm, 93–219 g. Probes only; no CDUs, no cold plates.
01 / Leak points
Rack elevation · six leak sites marked
Where the points are
The unit and cold plates appear as leak sites.
| Row | Sites |
|---|---|
| Inside the rack | cold plates; flexible hoses; manifolds |
| Boundary, route | unit connections; quick-disconnects; supply and return |
| Indicators, causes | extra top-up; pressure variation; air purging; unsealed fitting; gasket wear |
02 / Five models
Difference is power and output
EMS-LD-P2
Controller-powered, audible and visible alarm.
EMS-LD-P3
24 VAC/VDC supply, 1 relay output.
EMS-LD-P4
24 VAC/VDC supply, 2 relay outputs.
EMS-LD-P5
Controller port, 2.0 m uplink, 0.3–6.0 m leak cable.
03 / Ladder
One row per model, deciding figures
Each row links to the datasheet with the full parameter set.
| Code | Type | Power | Relays, local alarm |
|---|---|---|---|
| EMS-LD-P1 | surface probe | from controller | none, no alarm |
| EMS-LD-P2 | surface probe | from controller | none, audible and visible |
| EMS-LD-P3 | surface probe, single relay | isolated 24 VAC/VDC | 1, no alarm |
| EMS-LD-P4 | surface probe, dual relay | isolated 24 VAC/VDC | 2, no alarm |
| EMS-LD-P5 | rope-type rack probe | controller port | none, reports to host |
| Parameter | EMS-LD-P2 |
|---|---|
| Probe height above surface | 0–4.8 mm (0–0.19 in), adjustable |
| Leader cable | 4.3 m (14 ft), non-sensing |
| Body, weight | 39.4 × 50.8 × 25.4 mm; 93–219 g |

04 / Rack probe
Short runs where a reel does not fit
Six metres covers a manifold and hose set.
| Leak-cable lengths | 0.3 m to 6.0 m |
|---|---|
| Tested against | 10 % to 55 % glycol |
| Sensor ambient | 5 to +55 °C, to 2,000 m |
| Leak-cable rating | 0 to +75 °C |
| Supplied with | 2.0 m uplink · bracket · 2 clips · harness |
05 / Comparison
Two strategies
Probe or rope
| Question | Point probe | Locating rope | |
|---|---|---|---|
| Leak point known, countable | yes — one probe per point | no — continuous route coverage | |
| Coverage | one point | 1 to 500 m continuous | |
| Distance in the alarm | no | yes, 0.1 m position resolution | |
| Local alarm without a panel | yes (P2) | no | |
| Surface, cost, fit | the probe face | the run, dried 6–48 h; per point; disconnects, seals | per metre; serpentine, pipe routes |
A fitting inside a closed rack can only be instrumented. The rope's rows are on the locating rope page.
06 / Mounting
Height, hold-downs, leader
1 · Set height
0 to 4.8 mm above the surface.
2 · Fix the probe
2 hold-down clips per probe.
3 · Record the leader
4.3 m cannot be located.
4 · Wire the output
Dry contact into the BMS or DCIM.
5 · Containment
Valve closes, alert to the on-call team.
6 · Proof test
At commissioning, then yearly.
