- Page 3 GENERAL DESCRIPTION The Stevens SDX ( Figure 1) is a sensing device designed for water-level measurement applications. It is totally sealed for direct insertion into the media to be monitored, and offers multiple applications. Low range units are ideal for open channel flow applications.
- Page 4 A pressure transducer is used as the primary sensing element, and measures the water depth by sensing pressure above the unit. Internal circuitry within the SDX housing converts the signal to a 4-20 milliampere (mA) output, with 4 mA corresponding to zero depth (atmospheric pressure) and 20 mA to rated depth for selected range. Power for the two-wire current loop is derived from an external power supply.
- Page 5 GENERAL The Stevens SDX is a sealed unit that is suitable for submersion in water. The SDX is an isolated (floating) electrical device. Connect the SDX, an appropriate direct current loop power supply, and the receiving device (recorder, etc.) in a series loop.
- Page 6 Replace the desiccant cartridge when the indicating crystals have turned from blue to pink. If used with a flume, weir, or stilling well, it should be kept clear of obstructions, debris, or silt. When cleaning, the SDX should be removed prior to hosing out the channel, tank, or well.
