TRM-UST-LO is a designed to quickly detect lube oil, hydraulic oil or transformer oil (mineral oil) in small confined spaces. Examples are the interstitial space between the wall of a double wall tank, at low points in double containment piping or in low point sumps or drip-Ts.
TRM-UST-LO is small in both diameter and rigid length. This design feature allows the sensor to be inserted into the limited space between inner and outer tanks shells or similar tight passages. TRM-UST-LO is available in one size: 2 ½” long x ½” diameter. The outer surface is SS316 stainless steel
TRM-UST is supplied with 2m (6ft) of tray rated, outdoor, two wire leader cable (longer lengths can be supplied on request).
The recommended monitoring option for TRM-UST is TRM-Easy5-Relay or TRM-Easy5-Panel. Each TRM-Easy5-relay or Panel can monitor two TRM-UST-LO probes. A separate 250V / 8A SPST (NO) contact is provided for each probe and a third contact is provided for a local or remote alarm unit.
CSA Group has examined TRM-UST and considers the sensor to be “Simple Apparatus” per CSA /EN/IEC/UL 60079-11 Clauses 5.7 a and b. As such TRM-UST-LO may be installed in hazardous areas. When monitored by TRM-Easy5-Relay or TRM-Easy5-Panel the TRM-UST-LO can be installed in CID2 areas without additional protection. Installation in CID1 area requires a separate zener barrier.
Key Features
Form Factor:
- Small diameter, short length cylindrical probe
Dimensions:
- ½ ” diameter x 2 ½” rigid length
Leader/Jumper cable:
- Supplied with factory standard 2 m (6 feet) of leader cable. (longer leader cable can be quoted on request) Leader cable can be spliced to extended length jumper cable in the field. The maximum recommended jumper cable per TRM-UST -LO probe is 300m (1000 ft)
Integrity Monitoring:
- Loss of cable continuity is signaled as an ALARM condition as is detection of either fuel or water.
Response time:
- Lube Oil, Mineral Oil, Hydraulic Oil < 90 seconds at 20C
- Water – no response
Non-Resettable:
- Because of the heavy, non-volatile, nature of the target oils, the sensor will not drain or evaporate to a reset condition. TRM-UST-LO should be consider to be a “one use” sensor.
Simple Apparatus Statement:
- CSA Group has examined TRM-UST and considers the sensor to be “Simple Apparatus” per CSA /EN/IEC/UL 60079-11 Clauses 5.7 a and b. When monitored by the TRM-Easy5-Relay or TRM-Easy5-Panel, the TRM-UST-LO probe(s) can be installed in CID2 hazardous areas without additional protection. A zener barrier is required only if the probe is installed ins CID1 areas.
Recommended monitoring options:
- TRM-Easy5-Relay or TRM-Easy5-Panel
