The Druck PTX661 Pressure Transmitter has been designed for use in extremely harsh environments in both on-shore and off-shore Oil Drilling operations where high shock and vibration is likely to be encountered. The transmitter is available in both the 1502 and 2202 WECO wing union configurations, both of which are NACE sour gas compatible.

The PTX 661 differs from other hammer union pressure transmitters in that it has a replaceable pressure transmitter insert PTX 721-8518 which substantially reduces the cost of total transmitter replacement. With a 2 kHz response time, the device is suitable for measuring static and dynamic mud pressure.

The PTX 661 incorporates Druck's proprietary high-accuracy silicon sensor with up to 2.5 times better accuracy than many competitive devices. The low-volume oil-fill technology allows response times of faster than 2 kHz. The field proven 4 to 20 mA electronics, packaged in a rugged enclosure, provide power supply regulation, reverse polarity, overvoltage and EMC protection. The fully encapsulated design provides exceptional reliability in high shock and vibration environments.
