DCN0160
8. GLOSSARY OF TERMS
EU Engineering Units
Display units selection (inches, mm, feet, %, etc.)
URV Upper Range Value
Location on the transmitter sensor to set as the 20 mA output
LRV Lower Range Value
Location on the transmitter sensor to set as the 4 mA output
K0 Electronic Module Offset
Calibration data for each unique electronics module for the MT2000
KG Electronic Module Gain
Calibration data for each unique electronics module for the MT2000
BLK Blanking
Area at the top of the probe that you do not want monitored for process signal return. Usually increased by a value
of 4 per inch of nozzle.
Default factory value of 210.
THV Threshold Voltage
Minimum value that the return pulse voltage must be to indicate to the electronics it is a real value. Typical factory
value to 1.5.
GS Gain
One of four different values (1,2,3,4) which tell the electronics which algorithm to use in determining the value of the
return pulse.
HTP High Trim Point
Reference point near the area at which the high Engineering Units value for the transmitter will be set. To be set
prior to LRV and URV.
LTP Low Trim Point
Reference point near the area at which the low Engineering Units value for the transmitter will be set. To be set
prior to LRV and URV.
ULD Ultra-Low Dielectric Mode
Method of operation of the MT2000 that allows its use in situations where there is no detectable signal along the
length of the probe. Typically used in solids with a DC above 1.3 and below 2.0.
LT Linearization Table
Twenty step table inside the MT2000 electronics which can be used to correct the raw signal in situations where the
output is not linear
Stilling Well
Metallic Sleeve that the MT2000 probe is inserted inside. Allows probe to be used in lower DC and in situations
where there is significant turbulence.
Coax Probe
Probe style similar to the MT2000 installed in a Probe Well but with a much smaller diameter pipe. Can be inserted
through a ¾” NPT fitting. Typically used on very clean fluids or compressed gas products.
