A vast range of position sensing requirements and applications exist within the oil and gas sector, ranging from valve actuators to down-hole drilling equipment to deep-sea ROVs and sea-bed installations. Nevertheless, there is a common factor – safe and reliable operation in harsh conditions.
Position Sensors for Oil & Gas Applications
Zettlex standard and custom sensors are supplied to equipment manufacturers and system integrators in the oil and gas industry. The sensors are used in a variety of on-shore, off-shore, sub-sea and downstream applications, including:
- Liquid flow-monitors and meters (including ATEX certified)
- Valve and actuator position transmitters with 4-20mA, NAMUR and HART electrical outputs (including ATEX certified)
- Down hole actuator position control sensors
- Submersible ROV manipulator, rudder and hydroplane actuators sensors
- Winding gear position and speed sensors
- Brushless DC motor encoders for commutation and position control
Oil & Gas Application Requirements
Technical requirements within the oil & gas sector typically include:
- High-temperature operation at >125Celsius in down hole applications
- 2 wire 4-20mA, NAMUR, and HART electrical outputs
- Intrinsically safe operation with ATEX or CSA certification
- Explosion proof, high pressure or pressure compensated enclosures
- Electrically duplex or triplex operation
- Use of non-flammable, flame retardant and corrosion resistant materials
- High MTBF
