Sonotronics’ depth telemetry transmitters transmit their depth by varying the pulse interval time between pings. For example, a tag at 0psi at the surface may have an interval time of 650ms, and a full scale pressure of 100psi with a corresponding interval time of 2050ms. Depth transmitters come in 50, 100, 200, 300, and 500psi models. The accuracy of these transmitters is +/- 2% of full scale.

Sonotronics is now offering versions of its acoustic transmitters as modules that use external power sources. MO: MODULE ONLY GENERATORS CHP-MO-HP Sonotronics is now offering versions of its acoustic transmitters as modules that use external power sources. The CHP-MO-HP may be mounted on an instrument package or underwater vehicle, taking advantage of existing onboard power sources. The 2 wire version of the CHP-MO-HP will begin transmission of a coded sequence as soon as power is applied, and alternatively a 3 wire version is available that allows separate transmit control. Key specs: 16mm (dia) x 40mm (length) External Supply: 2.8V-5.5VDC 75ma max, 2ma ave Frequencies: 32-40kHz, 69-83 kHz, crystal controlled Source level: up to 150db re 1uPascal @ 1m EMT-01-3HP-MO 32mm (dia) x 85mm (length) External Supply: 4.5V-15VDC 500ma transmit Frequecies: 32-40kHz crystal controlled Source level: up to 165db re 1uPascal @ 1m 4 wire (1m water blocked, jacketed cable) V+ = Red GND = BLACK Control+ (C+) = Orange GND = Brown Operation: with power applied to Red/Black, C+ open = off, C+ to GND = transmit

Coded High Power transmitters generate a unique aural sequence, as well as unique combinations of frequency and ping interval allowing detection by both passive and active receivers. The CHP series of transmitters provide maximum detection ranges for use with pelagic studies or in areas of high noise. CHP TRANSMITTERS Coded High Power transmitters generate a unique aural sequence, as well as unique combinations of frequency and ping interval allowing detection by both passive and active receivers. The CHP series of transmitters provide maximum detection ranges for use with pelagic studies or in areas of high noise. Coded High Powered Transmitters Notes Range is typical under good conditions, using a Sonotronics active receiver and directional hydrophone. Autonomy based on a ping rate of once per second. Extened lifetimes are available by cycling the transmitters, please contact Sonotronics for more details CHP transmitters are by default produced with flat ends and small holes for an external mount, but may be ordered with rounded ends for internal implant.

Acoustic Transmitters and Receivers -Sonotronics offers an array of tracking products built on the concept of an Integrated Tracking Approach – a method that permits interoperability between product types, as well as forward and backward compatibility. TRACKING PRODUCTS Sonotronics offers an array of tracking products built on the concept of an Integrated Tracking Approach – a method that permits interoperability between product types, as well as forward and backward compatibility. As an example, recently a transmitter used to tag a fish 14 years earlier was detected by a modern MANTRAK receiver, and recovered on a lake bottom by use of an Underwater Diver Receiver (UDR) used primarily for the recovery of tagged equipment. This flexibility and consistency protects your investment in equipment, and allows for collaboration between groups with different interests: many universities use Sonotronics passive tracking products for long term fisheries studies, while at the same institution, an engineering group uses equipment tracking transmitters to tag submerged electronics packages for later retrieval, and both groups use the same active tracking receivers to obtain real-time information on either fish or equipment location and associated telemetry. Although this equipment is highly compatible, there are some detailed differences that help in particular applications: for example Equipment Marking Transmitters (EMTs) the same internal electronics as passive tracking tags used in fisheries research, the EMTs are housed in rugged, brightly colored PVC, with large mounting holes allowing use of standard zip ties for easy attachment to equipment. Based on the application area, Sonotronics tacking products are divided into 3 areas: Active Tracking, Passive Tracking, and Equipment Tracking.
