The Track-It™ Pressure Transmitter/Data Loggers with Digital Display are 24Vdc powered 4 wire transmitters that can also record up to 130,000 samples for logging, redundant data backup or archive. These are different from the Pressure Display standalone Data Loggers which do not transmit but store data internally and download through a USB cable to a PC. They can be configured to record both pressure or vacuum and ambient temperature or just pressure or vacuum alone to maximize data storage space. Real-time data, alarms and min/max information can be displayed on the multiline LCD. The unit is easily configured using the free downloadable Track-It™ Software. Simply connect the included USB cable to the logger and an open USB port on your PC and the Track-It™ Software automatically identifies the logger. Default configuration of the unit is 4mA = 0 and 20mA = full scale. Custom scaling over a smaller range can be accommodated using Track-It™ Software. The data logging sample storage rate can be set from 1 sample every 2 seconds up to 1 sample every 24 hours. The on board data storage is non-volatile so data will not be lost in the even of a power loss. Track-It™ Pressure Transmitter/Data Loggers can be ordered in various ranges. The logger is packaged in a rugged anodized aluminum and stainless steel housing and has a standard 1/4″ NPT fitting (1/2″ NPT for 8700 and 14,500 ranges).
