Echo Lost Timeout: This parameter allows adjustment of the time that the NCR Transmitter
waits after echo loss before producing a critical fault alarm.
Latching Mode: This parameter allows the selection of the behavior of the NCR transmitter in
the case of a critical error. If the Latching option is selected, the NCR transmitter will stay in
the critical error state until a user performs a hardware or software reset. This parameter is
only relevant to HART transmitters.
Envelope Level: Device will only read signal strength above Envelop level. Default envelop
level DB value is 5. User can set different value by referring to EFF curve based on site
situation
Equivalent-Time Sampling (ETS): Is a method of increasing the effective sampling rate.
ETS constructs a repetitive signal by capturing small parts of the waveform from successive
triggered acquisitions. This enables the accurate capture of signals whose frequency
components are much higher than the maximum sample rate.
Factory Mutual (FM): Provides third-party certification and approval of commercial and
industrial products, including Hazardous Location Electrical Equipment.
Field Device Tool (FDT): A general purpose application / tool that allows users to manage
many DTMs running their individual transmitters.
First Echo: This is used to differentiate between 2 echo's of similar amplitude and define the
primary echo
Flooded Interface measurement: There is no air layer in the tank, there is only fluid from the
process connector` to the interface.
Non-Contact Radar (NCR): A method commonly used to measure levels of liquid and solid
materials. Low frequency microwave pulses are guided by a metal probe and reflected off a
surface to determine levels in tanks.
®
HART Communications Protocol: Highway Addressable Remote Transducer (HART) is a
digital industrial automation protocol that is modulated over legacy 4-20 mA analog
instrumentation wiring
Honeywell Experion: An advanced distributed control system (DCS) and innovative software
applications to improve users' business performance and ensures reliable performance.
Honeywell Field Device Manager (FDM): A centralized asset management system for
remote configuration and maintenance of smart field devices based on HART, PROFIBUS and
Fieldbus FOUNDATION protocols.
Interface Measurement: Level measurements where to two liquids meet. For example, an oil
layer on top of water. Where the two meet is referred to as the interface level.
International Electrotechnical Commission Explosive Scheme (IECEx): IECEx
certification provides assurance that the strictest safety requirements of IEC International
Standards are met. Designed to facilitate the international trade of electrical equipment used in
explosive, hazardous environments.
