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.
