Product Overview
668-6 is a low cost series 668 differential pressure transmitter capable of measuring low pressures with a ±1% accuracy - ideally suited for proper building pressurization, HVAC and air flow control. Variable capacitance sensor design provides excellent sensitivity and long-term stability. Compact, lightweight design makes installation simple and easy. Units also feature reverse-polarity protection.
- Pressure range from 0-10 water column
- Good accuracy at low pressure ranges
- Provide exceptional value for ensuring control and minimizing costly out of specification conditions
- High overpressure rating eliminates possible damage to unit reducing unnecessary service time
- Operating temperature limits from 0 to 150°F (-18 to 65°C)
- Can withstand up to 10psig overpressure with no damage to the unit
- Supply voltage range from 12 to 30VDC and 4 to 20mA, 2-wire output
- Terminal strip electrical connection and 3/16˝ OD fitting for 1/4˝ ID tubing pressure connection
- Response time is <lt/> 60ms
- Terminal strip electric connection and fire-retardant glass filled polyester housing
