SensaTronics E4 Temperature Monitor

The SensaTronics E4 is a networked temperature monitoring device engineered for real-time environmental sensing in industrial, commercial, and IT infrastructure environments. It delivers accurate temperature measurement across -40°F to +140°F (-40°C to +60°C) using up to four dual-wire temperature probes, with measurements averaged over 5-second intervals. The unit integrates an internal web server for browser-based data access and supports standard network protocols including TCP/IP HTTP on Port 80, SNMP v1.0, Telnet, and DHCP. Data export to CSV format enables spreadsheet integration and historical logging via CRON scripts.

Measuring 4.25″ × 3.25″ × 1.38″ and weighing approximately 0.35 pounds, the E4 mounts via flanges to walls or racks in space-constrained deployments. RS-232C serial connectivity supplements Ethernet-based access for flexible system integration. The UL-listed power supply meets both FCC Class A requirements for commercial environments and Canadian Standards Association specifications, ensuring regulatory compliance across North American markets.
