FEATURES
Cleaner signal
- Increased wound length and dual coil winding increase signal strength and clarity while providing system redundancy
- Stronger, permanent magnets enable higher feedback levels
Reduced risk of flooding
- Pressure bulkheads on both ends prevent CCL flooding due to seal failure above or below the CCL
Longer lasting
- Tungsten carbide inserts protect the housing and subs by reducing wear on subs and housing
- Double wound coil provides a back-up system: if one strand breaks, you still get a signal
- Permanent magnets never require recharging
- Shock-proof PCB diode assembly
Compatible with industry standards
- Industry-standard connection threads
- High nickel alloy housing is non-magnetic and is suitable for harsh environments (CO2, H2S)
- Housing material meets API 5CT and NACE NR0175 standards
