The Vault Transmitter is the most robust of all SteamEye® transmitters. It utilizes a robust aluminum epoxy coated housing with potted electrical components to protect the transmitter from high temperature and condensation. By utilizing conductivity and temperature readings to determine trap condition (cold, ok, and blow thru), the Vault Transmitter excels in applications like vaults and tunnels. This transmitter is designed to be installed outside of the vault to help avoid stringent confined space entry regulations and reduce safety concerns of employees.
