Wireless Arrival Sensor
Normally, a wellhead is only a close distance to its separator shack and controller, or Scada RTU. The two locations aren’t far apart and using an armoured cable between them is quick and painless. For these cases, a normal Arrival Sensor may be used. However, sometimes the distance between wellhead and shack is too great or the trip between can be too difficult to traverse, causing great expense. In these cases, the best method is to install a Wireless Arrival Sensor. PIT is a proud provider of Wireless Arrival Sensors to assist with these situations.
OKC’s LinkMate Wireless Switch Router is PIT’s choice for Wireless Arrival Sensors. Safe, compact and durable, the LinkMate is a cost-effective and easy to use plunger arrival detection system for your wellhead to shack connection. Featuring four switch inputs and four switch outputs, a switch event occurs when any switch changes from an On to an Off state, or vice versa. The signal from the switch event is transmitted via omnidirectional weather resistant antennas and is connected to its paired device from up to 1000 feet away!
The system consists of two small boxes. One box is located in the shack and consists of the omnidirectional antenna. The second box contains the Arrival Sensor and the transmitter. Couple these with a solar panel for each box and you have a fully functional, easy to install, Wireless Sensor. The system is Intrinsically safe, Class 1, Div 1 too!
Why Use A Wireless Arrival Sensor?
Occasionally, wellheads and shacks will be a significant distance apart. Running large amounts of cable between the two locations can be extremely expensive and labour intensive. While a Wireless Arrival Sensor is more expensive than a few feet of cable, there reaches a point where the cost of the cable, plus the time and labour, no longer makes a wired connection feasible. This is where a wireless feature can save you a whole lot of time and money.
