DC 22

Pressure and temperature submersible logger

Explorer, the autonomous data collector
Submersible depth/temperature recording with RS 232 link

The Explorer DC-22 is an autonomous battery powered instrument designed to record pressure/water depth and temperature over long periods. Two versions are offered:

DC-22: The sensor, electronics and battery are housed in a sealed stainless steel (ø22mm) “cigar tube”, for submersible deployment. For data read-out the DC-22 must be recovered from the measurement point. The O-ring sealed end cap is then removed to access the data port.
DC-22 G: Utilises a sealed sensor and electronics for submersible deployment. The sensor is connected by sealed cable to a battery housing (ø46mm) which incorporates the data read-out port. This arrangement allows for easier data recovery from fixed installations. The sensor can be absolute or vented gauge, the cable carries the vent tube for gauge version sensors. Due to its larger size the battery life is significantly increased. However for space limited applications the DC-22G is also available with a smaller battery housing (ø22mm).
