SigNET SWGN Induction Loop, 1Khz Sine Wave Generator £44.03
Description
Does your induction loop installations comply with current British standards?
BS8300 (the code of practice for the design of buildings and their approaches to meet the needs of disabled people) states that all loop systems should conform to BS7594 and BS EN60118-4. The best way to ensure compliance is to use SigNET’s new FoSmeter / SWgen range of induction loop testing equipment.
The range comprises the SWGen Sine Wave Generator and the FoSmeter Magnetic Field Strength Meter. Used together, they represent the most reliable method of ensuring that an AFILS system is working correctly.
A combined Sine Wave Generator and Magnetic Field Strength Meter (the FoSmeter+) and a combined Magnetic Field Strength Meter and Loop Listening Device (the FoSmeter H) are also available.
Audio frequency induction loop systems require careful testing and calibration prior to operation. The most efficient way of doing this is to use a SWGen Sine Wave Generator and a FoSmeter Magnetic Field Strength Meter.
BS7594 recommends that the minimum magnetic field strength of an induction loop system over a covered area should be 100mA RMS per metre. The most effective and reliable way of ensuring this requirement is met is to measure the magnetic field strength of a steady output from the induction loop amplifier.

Technical Specifications
- The SWGN can be connected to the line level input of most audio-frequency induction loop amplifiers. It has a fixed level output of approx. 400mV RMS and a crest factor of approx. 4:1.
- The following leads are available for connecting the SWGen to a PDA Range induction loop system:-
- AL1: 3.5mm jack to 3.5mm jack lead
- AL2: 3.5mm jack to double phono lead
- AL3: 3.5mm jack to pre-cut end lead
- All leads are 10m long.
- For customers wishing to make their own connection leads, please note that TIP = Audio+; Ring = Audio -; SCREEN = internal ground.
- Order code: SWGN
- Dimensions (WxHxD): 64 x 101 x 22mm
- Pink noise output level: 400mV RMS
- Pink noise crest factor: 4:1 approx.
- Pink noise output socket: 3.5mm jack
- Controls: 1 x Power on/off switch
- Indicators: 1 x Power on LED
- Battery requirements: 1 x PP3
Features
- A new range of cost-effective induction loop testing equipment from SigNET
- Ideal for testing and maintaining virtually all makes of induction loop system to ensure compliance with industry accepted standards
- The range comprises a sine wave generator (the SWGen) and a selection of magnetic field strength meters (the FoSmeter, FoSmeter + and FoSmeter H)
- The SWGen pink noise generator can be connected to the line level input of most induction loop systems and provides a constant 400mV RMS balanced signal which can be much more accurately measured than the variable output of music or speech
- The FoSmeter range of magnetic field strength meters can be used to measure the magnetic field strength of any AFILS system in increments of 3dB (relative to 100mA/m)
- All FoSmeter variants feature an ‘A-weighted’ filter to match the characteristics of the human ear and minimise the effects of mains or electrical hum and a High/Low gain switch* to help monitor the effects of crosstalk or overspill
