Schlumberger’s downhole pressure gauge is one of the most famous star products in the industry, and its good product performance and service are widely trusted by oilfield service companies and oilfields.

Schlumberger

Schlumberger is the world's leading oilfield technology services company, mainly engaged in oilfield services and seismic data acquisition and processing. Headquartered in New York, Paris and The Hague, with branches in more than 140 countries around the world. It first entered China's oil industry in 1980 to carry out oilfield service business. Schlumberger’s downhole pressure gauges are well-known around the world, and the stability and accuracy of the equipment are at the industry benchmark.

Schlumberger’s Downhole Manometer Models

Schlumberger’s downhole pressure gauges mainly have 5 models, 2 basic models, TCQR Signature CQG* Crystal Quartz Gauge and TCQR Signature Crystal Quartz Gauge. The range is 16000psi [110Mpa], and the high temperature is up to 175℃. The TCQR Signature Crystal Quartz Gauge supports wireless signal transmission. In addition, there are high temperature type, high temperature and high pressure type and ultra-high temperature type. The highest temperature resistance is 225℃, and the maximum pressure is 30000psi.

PPM-S314C High Temp Pressure Sensor

Downhole pressure gauge related sensors

PPM-S314C oilfield high temperature pressure sensor is a special pressure sensor for downhole in oilfield, and it is also the core component of downhole pressure gauge. High temperature resistance, small size, the structure adopts double ring seal, which ensures the sealing problem under high temperature and high pressure. The highest pressure reaches 30000psi, and it has excellent sensitivity, reaching 4mV/V.
