BENTLY NEVADA Model 3500/50 Tachometer Module

The portable on-site high-precision calibration instrument ZTD98 for power plant turbine monitoring instruments (TSI) and pneumatic actuators combines the experience of on-site debugging with the latest large-scale integrated circuit and microcomputer technology in China, and adopts a novel and unique circuit structure. This product fills the gap at home and abroad and won the Shandong Province Science and Technology Progress Award in 1999.
ZTD98 has a wide range of applications
Can be used for the Bently 30003500 model in the United States; Verify all monitoring instruments (TSI), including German Phillip, MMS6000, and other domestic and international instruments.
ZTD98 operates in both AC and DC power supply modes
It can be powered by 220V AC or continuously used for dozens of hours using the battery inside the machine. Therefore, the device can verify the TSI system on site without using AC power.
ZTD98 has very high verification accuracy
Regardless of the use of either AC or DC power supply methods, this device can accurately simulate the output signal of the probe during the actual operation of the steam turbine. Taking the eddy current probe with a sensitivity of 7.874V/mm as an example, a 12 bit LCD display shows true peak to peak amplitude with an accuracy of 1 μ M.
ZTD98 can verify various channels and corresponding alarm output systems of the TSI system, and establish a file of on-site actual verification data
When debugging and verifying channels such as shaft vibration, tile vibration, composite vibration, various differential expansion, displacement, eccentricity, speed, and zero speed, the device can also accurately collect 4-20mA output signals from the aforementioned channels in the TSI system, and store these output signals in the RAM of the device with a power loss protection circuit. After returning to the office from the site, the RS232 interface of the device can be used to transmit the actual verification data of these channels to the computer. Enable the actual verification data of these channels to be saved, displayed, and printed.
ZTD98 is particularly convenient to use
When using this device, the sensitivity of each probe can be set arbitrarily μ Verification of m display value in TSI system; The voltage display value can also be used to verify the TSI system. The EEPROM inside the device can store the sensitivity of each probe set for a long time. When verifying the power plant turbine monitoring instrument (TSI) with this device, it is basically only necessary to add the output signal of the channel to the on-site TSI system terminal according to the operating manual, which is very convenient. It can provide multiple verification functions to adapt to the verification of TSI systems of various models and manufacturers.
ZTD98 has the function of debugging pneumatic actuators
This device has one channel that can provide a 4-20 mA command signal, and another channel that can provide a 24V constant voltage source with the same sampling circuit as DCS. A 12 bit LCD display displays both command current and position feedback current simultaneously. Due to the fact that the device can operate using the internal battery and provide a 24V constant voltage source with the same sampling circuit as DCS, it brings great convenience to the debugging of pneumatic actuators.
