Product Description
The DLS-400 combines years of monitoring experience with advanced wireless communications in one complete system. The system is designed for long- term monitoring and transmission of data from sensors supplying 4-20 mA, 0-2.5V signals, or SDI-12 communications. The sealed design significantly reduces site visits. The NEMA 4/IP65 housing has a hinged sealing cover for protection.
The data monitoring function allows multiple readings to be stored and the sample rate is adjustable from once every second to once every day. Additionally, an accumulated total is recorded and displayed. Data can be downloaded through a wide variety of wired and wireless communication options and then graphed or exported via a CSV file. Optimum Instruments is directly connected to a wide range of network providers to be able to provide service throughout North America. And because we are connected directly, we have two way communications with our Data Dolphin data loggers.
The Data Dolphin provides the accuracy of a laboratory instrument in the harsh conditions of the field environment. The ultra-high resolution 24 bit analog to digital section provides 8 single ended inputs or 4 differential bipolar inputs (or a combination of both) with resolution down to 90 nanovolts (.00000009 volts). This allows most sensors to be directly connected without any signal conditioning. It's wide range of input voltages allows for you to attach a wide range of different input types. There are an additional four inputs that can be user selected as pulse, status, event start/stop or analog inputs.
