Description
The Subsea Data logger is a proprietary data logger designed by DLM for use in the offshore industry. Comprising of multiple onboard sensors and with extra capacity for external mV or mA inputs, the DL-3.0 can sample onboard and external sensors at customisable sample rates of up to 800Hz.
The data logger is housed within a compact stainless steel 316 enclosure with mounting holes for easy integration into existing or new subsea equipment. Ideal for long or short-term deployments on offshore and subsea structures, but also ideal for R&D projects where verification data is required to compare against computer models.
