Abstract

A measurement device with a cylindrical housing (2), with a sensor element and with an adjustment element (6) made, for example, as a potentiometer, for setting at least one parameter of the measurement device. The measurement device (1) is especially easily and still accurately and reproducibly settable by there being at least one rotary adjustment ring, the adjustment ring being made as a housing sleeve (7) for setting the parameter.

Claims

1. Measurement device comprising:

a cylindrical housing with a sensor element located therein and

an adjustment element for setting at least one parameter of the measurement device,

wherein at least one setting element is provided for setting the at least one adjustment element, said setting element comprising a rotary sleeve mounted over a portion of said cylindrical housing, and

wherein at least one scale is provided on at least one of an outer surface of the housing and the sleeve for indicating a value of the parameter set based on the position of the sleeve relative to the housing wherein the rotary sleeve has internal teeth, wherein a gear is provided within the housing, the gear having external teeth for co-acting with said internal teeth, and wherein the gear interacts with the adjustment element.

2. Measurement device as claimed in claim 1, further comprising means for transmitting the position of the rotary sleeve on the housing to the adjustment element.

3. Measurement device as claimed in claim 1, wherein the gear is connected via a shaft to the adjustment element.

4. Measurement device as claimed in claim 1, wherein the internal teeth are axially oriented on the rotary sleeve and wherein the axis of the gear is located parallel to the lengthwise axis of the housing.

5. Measurement device as claimed in claim 4, wherein there are two rotary sleeves and two gears, the internal teeth of the two rotary sleeves being arranged concentrically to one another.

6. Measurement device as claimed in claim 5, wherein the two gears are located axially and radially offset relative to one another.

7. Measurement device as claimed in claim 1, wherein the internal teeth are radially oriented in the rotary sleeve, wherein the external teeth of the gear are radially oriented and the axis of the gear is located perpendicular to the lengthwise axis of the housing.

8. Measurement device as claimed in claim 7, wherein there are two rotary sleeves and two gears, the internal teeth of the two housing sleeves and the two gears being located axially offset relative to one another with respect to an axis of rotation of the rotary sleeves.

9. Measurement device as claimed in claim 8, wherein a locking mechanism is provided for locking the rotary sleeve.

10. Measurement device as claimed in claim 9, wherein the locking mechanism comprises a sleeve or partial sleeve, the sleeve or partial sleeve at least partially extending over the housing or the rotary sleeves.

11. Measurement device as claimed in claim 10, wherein the sleeve or the partial sleeve is made of a transparent material and comprises a magnifier.

12. Measurement device as claimed in claim 1, wherein a locking mechanism is provided for locking the rotary sleeve.

13. Measurement device as claimed in claim 1, wherein said teeth lock the rotary sleeve on the housing and wherein the rotary sleeve is axially movable for disengaging the internal and external teeth and thereby enabling adjusting of a parameter.

14. Measurement device as claimed in claim 1, wherein the sensor is at least one of a potentiometer, a flow sensor or monitor, a pressure sensor, and a temperature sensor.
