Flocorp Tracer 1000 LTT1 Guided Wave Radar Level Transmitter

Flocorp Tracer 1000 LTT1 Guided Wave Radar Level Transmitter provides continuous level measurement and point level detection in liquids and solids, with analog and switching output. This innovative device has almost no installation restrictions – it can be mounted in small tanks, tall and narrow nozzles and it measures precisely even with difficult tank geometries or close to interfering structures.

Factory settings may be configured via the HART® Communication protocol. Tracer 1000 is ideal for various types of processing and storage applications and has an exceptional performance in liquids with low reflectivity such as oils and hydrocarbons.

Electrical Specifications
Output Functions The Tracer 1000 is an active, single ended, non-isolated, 3 or 4 wire analog output transmitter.
Analog Output (Active) Current output 4-20mA: The span between the lower range value [4mA] and the upper range value [20mA]
is equal to 0-100% of the continuous level measurement reading as a factory default. Output can be inverted.
Total Load Resistance < 500Ω: HART resistor approx. 250Ω
+ load resistance approx. 250Ω if the current output is connected to a device with an inner resistance of approx. 250Ω, then there is no additional external HART resistor necessary. In that case, the HART modem is connected in parallel to the current output wires.
Lower Range Value 4.0mA (span 0%)
Upper Range Span 20.0mA (span 100%)
Response Time 0.5s (default), 2s 5s (selectable)
Temperature Drift Less than .0078 in/ºF change in ambient
Switch Output DC Switch, PNP, Active, Max. Load 200 mA Current.
Supply Voltage 12-30VDC (reverse-polarity protected)
Current Consumption < 50mA at 24 VDC (no burden)
Start-Up Time < 6s
Cable Terminals Screwless, cage clamp terminal block for stranded and solid wires AWG 22-14.
Measurement Specifications
