Product details - Trap Transmitter

Trap transmitter with removeable magnet to activate the transmitter.

Cape ground squirrel caught in a trap.

Description:

Trap transmitters are standard or high power two stage transmitters used to detect if a trap has been triggered. Animal ethics and moral obligations are becoming more and more of a factor in todays society, but time, expense and logistics of checking traps in remote areas can be a limiting factor. In these situations it is great to be able to tune a receiver to the correct frequency and tell simply by the change in pulse rate if the trap is triggered or not. The transmitters can operate in a fail safe mode, running continuously at a slow base pulse rate but stopping, or changing the pulse rate, when the trap is triggered. There are many variations to the theme.

Feature summary:
Transmitter life	Determined by pulse rate and battery size. The range varies from 1.5 months to 4 years. Contact us for life estimates.
Transmitter range	The range of trap transmitters, like all transmitters, depends upon its antenna, the environment and the quality of the receiving equipment. With a good whip antenna and line of sight; ground-to-ground ranges in the order of 2-8 kilometres are typical depending if you are using a standard or high power two stage transmitter.
Pulse rates	Determined on consultation with Sirtrack to achieve your desired result.
Pulse width	Typically 18ms.
Housing	Transmitters and cells are hermetically sealed with inert epoxy resins that are available in a range of colours upon request. Dental acrylic is often used for extra stength.
Activation	The trap transmitter is activated by a magnet. There are a variety of options on how the trap can trigger the on/off operation of the transmitter depending on the design required.
Antenna	Typically stranded stainless steel wire with nylon coating of a variety of gauges and lengths. The antenna is usually always a whip antenna for maximum range.
