mAs SENSORS - 90M9 and 90M10 |
|
|
|
|

The mA and mAs Sensors come in both INVASIVE and NON-INVASIVE
Clamp On Models |

|
| 90M9 Invasive Sensor
|
 |
90M9
Invasive Sensor - (requires kV sensor to be in beam) |
| Full-scale: |
2000
mA or 9999 mAs |
| mA accuracy: |
0.2% of reading at dc plus resolution of +/-0.015 mA or 3-4 digits |
| mAs accuracy
(1-s pulse): |
5 µAs or 0.2 % of reading; resolution of 0.001 mA |
|
| |
| The mAs sensor connects to the 4-pin connector labeled mAs of model 9096/4086 using a standard S-Video cable and to the x-ray generator with safety shrouded banana jacks. It is intended to be inserted in series with the x-ray generator return. The value of mAs is computed by summing mA values during the part of the kV waveform (requires kV
sensor in beam) defined by the same thresholds that are applied to determine its width,
generally 75% of kVp. Average mA is mAs divided by this width. |

90M10 Non-Invasive Clamp On Sensor
|
 |
90M10
Non-Invasive Clamp On Sensor - (requires kV sensor to be in beam) |
| Full-scale: |
0-2000 mA or 0-9999 mAs Radcal 9096 ACCU-PRO or Radcal 4086 ACCU-kV (2-2000 mA when used with model 9095) |
| mA accuracy: |
± 4% of reading (Limited by 0.6mA RMS noise below 15mA) |
| mAs accuracy
(1-s pulse): |
± 4% of reading, (Limited by 0.6mAs RMS noise below 15mA) |
|

The mAs sensor connects to the 4-pin connector labeled mAs of model 9096/4086
using a standard S-Video cable and couples to the x-ray generator by clamping to the x-ray
anode HV cable (clamps up to 23mm diameter). The value of mAs is computed by summing
mA values during the part of the kV waveform (requires kV sensor in beam) defined by the
same thresholds that are applied to determine its width, generally 75% of kVp. To measure
Anode current, clamp on the anode cable with the arrow on the clamp pointing towards the
X-ray tube. For best results, do not move clamp before and during a measurement. |
