Model Number: 408 DTZ-C-XX1S
Key Specifications/Special Features:
Brief introduction:Tachometer type DTZ-C-XX1Swhich is designed and manufactured by our factoryis a free-maintenance and free-adjustmentinstrument, for the high reliability theory is applied whiledesigning the instrument. It is used for turbo-expanderespeciallyTachometer type DTZ-C-XX1S has functions ofmeasuring, displaying rotation speed and controllingCan not only be used for the field instrument but also beconnected with computer or DCS system by outputting4-20mA DC current signal of rotation speedApplyingthe tachometer, central computer only need to receivevarious process parameters from the field instrument andtransfer the control parameter to front-end processor
Monitoring and controlling of field equipment are assignedto the intelligent tachometer
Therefore, if centralcomputer has broken once, field equipment can still becontrolled
Thus, significant risk is decreased greatly andsystem reliability can be increased
In the inner of tachometer, shaping circuit forinputting the signal of rotation speed, the circuit of chipmicroprocessor and the circuit for outputting the standardcurrent in the tachometer have mutually be isolated byphoto-couple
Signal of rotation speed is convertedinto 420mA standard current through DAC, thus it can bedirectly connected to terminal computer without beingisolated
Because some intermediate links are abridgedwhen applying the tachometer, reliability and accuracyof the system increase greatly
Can be stable to work under the influence of strongindustry interference because anti-interference technique isadopted while designing the tachometer
User may set operant value of 3 relays on-line, tachometer offers 3 normally open/stopped contacts of 3relays
So it can be agilely
Setting value would notlose,when the turbo-expander stops or turns off the powersupply of tachometer
Main functions:
- Display the rotation speed in 5 figures with LED
- Output 4-20mA DC current of rotation speed
- Signal in isolation
- May set measuring range as 3x104rpm, 5x104rpm, 10x104rpmor 20x104rpm
- May look up measuring range on-line
- May set operant values of 3 relaysand may set andlook up values on-line
- Output normally open/closed contacts of 3 relays
