Converting gate opening angle signal to DC standard signal
 

We are using the synchronous transmitter (SELF-SYNCH) to measure the opening angle of an intake gate in the river and send the output signal of the transmitter to the synchronous receiver in a control room to display the opening angle. As a result of monitor system standardization, we want to convert the output signal (opening angle signal) into a standardized signal of 4 to 20 mA in DC for instrumentation without replacing or modifying the existing synchronous transmitter. Is there any converter suitable for this purpose? The precise operating angle range of the synchronous transmitter is unknown.

MS Word

We’d like to introduce our SELF-SYNCH Transmitter, model MXS, which is front configurable type. The MXS takes in the opening angle signal (with a measurement range of 0° to 360° and a span of 60° to 360° ) from the synchronous transmitter (SELF-SYNCH) and convert the signal into an analog signal. The opening angle range and other initial settings are set in the DATA display and ITEM No. display on the front panel of the MXS. These displays are operated with the respective UP-DOWN Keys on the front panel. If the opening angle range is unknown at the time of 0% position setting in ITEM 03 and 100% position setting in ITEM 04 of the MXS, the synchronous transmitter can be moved to the fully closed position and fully opened position. By double clicking the DATA Key then, the 0% and 100% positions will be programmed. For the setting method in detail, please refer to the specification sheet.
