PTX661 Pressure Transmitter (Drilling Mud Hammer Union Sensor) - DESCRIPTION
by Druck

The PTX 661 hammer union 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 the1502 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.
