Tachometer K1803.1 (K-1803.1, K 1803.1)
Tachometer K1803.1 designed for remote measurements of the speed and the direction of rotation of shaft diameters from 20mm to 1125mm main marine engines.
Class of accuracy:
- 1.0 - working with reversible shaft;
- 1.0 - for devices with zero within the range of measurement;
- 1.5 - for devices with a zero on the left.
Technical characteristics of the devices K1803.1 tachometers:
The tachometer has K1803.1 obscheklimaticheskoe rendition of "0";
The structure of the device include:
- The primary transmitter G113.1;
- Intermediate R1813.1 converter;
- Showing the device M1619.1;
Installation elements kit
- Single maintenance kit consisting of  R1813.1;
The range of the instrument measuring the tachometer K1803.1 and the number of rotor teeth, depending on the diameter of the shaft are given in Table. 1;
Standardized output signals to the analog output proportional to the frequency K1803.1 tachometer shaft rotation;
The limits of voltage changes the output signals:
- From 0 V to +10 V - when working with irreversible tachometer shafts;
- From-10V to +10 V - when working with a reversible shaft tachometer;
The voltage output tachometer K1803.1 corresponding to finite values ​​ranges - 10V;
Load resistance - from 2 ohms to 2 megohms;
Power supply is provided from a tachometer K1803.1 AC 220V 50 Hz or 400 Hz with a THD of 10%;
Power consumption does not exceed 20V ∙ A;
