TD-310
	A high accuracy Log complying with requirements of IMO, the TD-310 Doppler Speed Log has many signals' output function such as ship's speed and distance. The size of the units are reduced considerably(display unit is 1/14 in volume and 1/5 in mass compared to TD-501). Installation is simple on coastal and ocean going ships. Features: The TD-310 adopts paired beam system in which the sonic energy is directed ahead and astern. This virtually minimizes doppler shift errors caused by the ship's motions. Furthermore, by receiving the echoes selectively from about 3m below the ship's hull, the TD-310 minimizes adverse wake influences. By virtue of its non-protuding, flush mount design, the transducers of the TD-310 is completely free from the damaged caused by drift ice or wood. Retraction is not necessary before entering port or extended when leaving port. Total circmulative DISTANCE 1 and DISTANCE 2 are memorized for each display unit Up to 3 display units and 4 Analog meters can be connected Auxiliary output signals as standard Digital interface (IEC-61162-1 VBW,VLW) : 8 circuits 200 pulses/mile contact signals : 8 circuits Current signal(4-20 mA) : 1 circuit Voltage signal : 1 circuit Low cost and simplicity of installation All special cables are supplied by TOKIMEC Size of main units are reduced as such system can be installed with ease and low cost.
