Equipment Status Monitoring

"State-of-Health" Applications of Sensor Synergy Technology

The NEEM unit is ideally suited to monitor one to several sensors that provide equipment status information to manufacturers, service contractors and users.

NEEM enabled remote monitoring capabilities can indicate appliance failure, inefficient operation, the need for near-term service, and general "state-of-health" information.
Several of our customers have found that the NEEM is a cost-effective solution to controlling maintenance and service costs.
By monitoring key equipment features, the NEEM can help you better manage service and maintenance operations.
 
Three examples of this type of benefit:

1)       Monitor equipment to know if it is operational without periodic checks by maintenance staff.

2)       Monitor equipment to preemptively correct problems before high-valued equipment fails Unplanned equipment downtime can create very costly liabilities for both the equipment user and the equipment maker.

3)       Monitor multiple pieces of equipment to better schedule service calls in order to control costs



Operational Status --- Up or Down?

For some remote applications, where equipment is not in close proximity to operations staff, only the most basic status info is needed

Failure of HVAC equipment can have serious consequences unless immediate action is taken by service personnel. The use of NEEM units has proven to be a cost effective way to monitor the status of essential equipment.

In another application, a Sensor Synergy customer used a NEEM-115 unit to monitor the special HVAC equipment that they leased to their clients. When the leased equipment failed in a remote location, the NEEM unit sent an e-mail alert message to corporate headquarters and to the on-call technician. Maintenance personnel were dispatched to the problem site and the unit was back on line within 2 hours. Our customer received the ultimate compliment when their client said, "You guys are really on top of your game!"


Preemptive Service -- Condition Based Maintenance -- Find and fix a problem before it can halt operations

Using the NEEM to monitor key properties, the possibility of near-term equipment failure can often be predicted.

A key feature of Condition Based Maintenance is to perform maintenance operations because a measured feature suggests that a maintenance operation is needed. This is in contrast to the more commonly used "elapsed-time" approach to maintenance. For the elapsed-time approach, the calendar or clock indicates that a certain period of time has elapsed since the last maintenance operation and triggers the performance of the next maintenance operation in the sequence. Of course, using the elapsed-time approach, needless operations are performed and often critically needed operations are missed.

With Condition Based Maintenance, measured conditions trigger maintenance and repair operations not the calendar.

In one application, a Sensor Synergy customer used a NEEM-115 unit to monitor their special HVAC equipment that they lease to their clients. When the leased equipment failed in a remote location, the NEEM unit sent an e-mail alert message to corporate headquarters and to the on-call technician. Maintenance personnel were dispatched to the problem site and the unit was back on line within 2 hours. Our customer received the ultimate compliment when their client said, "You guys are really on top of your game!"

Combining Service Calls through Scheduling Close Proximity Facilities Based on Measured Conditions

By tracking key features, multiple, on-site maintenance visits can be combined and routed into a single service trip saving the costs of mulitple separate trips.

In some applications, multiple copies of similar equipment must be maintained in on-site service visits. For many types of equipment, similar maintenance operations may be needed but the time in which these operations are needed may not be known until an "in-the-field" failure occurs.

Using the NEEM equipment and provided software, similar equipment at multiple locations can be monitored with very little setup effort. The information collected by the NEEM can be used to schedule combined service trips that are planned to maximize the use of service technicians time. This effectively spreads the travel costs among multiple service stops.

In some cases, the added efficiency from servicing multiple locations with a single service trip can rapidly recover the costs of the remote monitoring equipment.

In addition to significantly improving the efficiency of the service trips, customers owning the equipment are pleased to have their equipment serviced in a scheduled and planned manner before it breaks . This is in contrast to the more common events in which vital equipment breaks in an unplanned and often expensive manner.
