T&D RTR-505-P Wireless Pulse Dataloggers
CHESTERLAND OH-February 20, 2012
CAS DataLoggers recently supplied the wireless datalogging solution the HVAC contractor who needed to perform power monitoring for client's 25 HVAC systems installed from a strip mall. The owner began searching to enjoy a compact yet cost-effective datalogging device might connect to most commercially-available power meters to measure the heartbeat output. Anticipating an additional request to monitor the mall's temperature and humidity, the contractor also needed this device become compatible with other datalogging models to measure other parameters including the temperature in a duct, the humidity of your airstream coming out of an air handler, etc. This solution would also need wireless communication to deliver adequate coverage in out-of-the-way spots additionally the would have to guide handheld data collection to save workers the time of checking each device manually, which were too time-consuming to help you keep their appointments with other clients and undertakings.
The contractor installed 5 T&D RTR-505-P Wireless Pulse Dataloggers to monitor the mall's HVAC system energy usage while using pulse output, connecting them to energy meters via several Continental Control Systems WattNode WNC-P devices to work using the data loggers current users 1 pulse per every watt hour. Additionally, a T&D TR-57DCi Handheld Data Collector was chosen for fast data accessibility. T&D RTR-505-P wireless loggers recorded pulse output taken from the mall's power meters, enabling cost-effective power monitoring--every hour users saw the energy consumption over the previous hour. Users could freely scale end result. Using the dataloggers' software, users converted the pulses back into energy to view kilowatt hours being a result. Workers could easily combine the 505-P with other T&D dataloggers, placing them in heating ducts and attaching them to air handlers to measure other parameters including temperature and humidity, giving the contractor a comprehensive system with the flexibility to handle various applications.
The compact T&D pulse data loggers were designed to record the alterations in pulse count for contact signals (such as switches, relays, and thermostats) and Lo/Hi voltage signals that occurred throughout a set recording interval. The devices were competent at recording the total pulse count coming from a start of recording and also allowed for a variety of commercially available sensors to be connected with the included input module, widening kids of possible applications without workers having to travel back adjust Base Units. Measuring voltage signals from 0 to 27V with a pulse response with the lowest of 0.5V or less, high of two.5V or more, even a maximum pulse response of 3,500 pulses per second, the info loggers featured extreme 16,000 reading storage capacity to keep logging for long periods. Capable of counting up to 61,439 pulses per reading, the loggers' clear LCD displays showed current readings along with status, logging capacity, measurement range exceeded, and more, as well as the dataloggers also offered options for wall mounts to cover all the out-of-the-way spaces.
The T&D data loggers offered convenient data accessibility--it was simple to instantly download all info via wireless communication using an RTR-505-P Base Unit. The wireless communication range from a Remote Unit and a Base Unit was about 500 feet (150 meters), and this range was easily extended by simply registering an RTR-500 as a Repeater to expand coverage. The datalogger's large logging capacity of up to 16,000 readings allowed users to set a recording interval of once a person and keep monitoring for 665 24 hour periods. It only took november 17 minutes for a base Unit to finish wirelessly downloading one RTR-505 Remote Unit at full logging capacity. Data could also be collected remotely via USB and LAN.
Utilizing a low energy consumption design, the data loggers' lithium batteries had an estimated battery life of about 10 months operating at normal temperature. If your contractor needed to boost logging duration, T&D 'L' model loggers featured a large capacity battery pack so that underneath the same conditions can continue for four years to save workers the trouble of replacing the battery.
Using the T&D handheld data collector, workers simply collected all of the data from as long ago as the parking lot, gathering and checking recorded data using the spot getting to moment manually gathering the data loggers. Recording settings with regard to example 'Recording Interval' and 'Recording Start' could also be made directly against the TR-57DCi into the loggers. Compatible with majority of T&D data loggers, the data collector stored an impressive 256,000 readings with an electric battery life roughly 100 days at sixty minutes of daily use. The collector's Liquid crystal display featured useful functions for quickly thumbing through the info. The T&D data collector could also communicate with a PC via USB.
The contractor benefited a number of ways following installation for the T&D RTR-505-P wireless pulse data loggers. These compact devices linked with a wide range of power meters. Enterprise needed to other parameters such as temperature and humidity, other T&D loggers could definitely be inserted your market mall's heating ducts and attached to air handlers to construct a comprehensive monitoring system with no versatility to measure regardless of the client needed. Data collection and organization the snap utilizing the loggers' wireless capability and the handheld data collector.
