APS400 | APS420 | APS600/602 | Cable Head | Spooler Box

The APS400 is a single piezo resistive permanent downhole gauge that measures pressure and temperature. Standard pressures are 1,000, 6,000, 10,000 PSIA. The transducer is designed for 150°C operating temperatures and is available in 316L Stainless (standard), Duplex 2205 and other custom metals upon request.

The APS400 is calibrated over the full operating temperature range and has a full scale pressure error of 0.2% and a resolution of 0.3 PSIA. The temperature error is 0.25°C with a resolution of .01°C.

The APS400 is ideal for slim applications as the OD is 0.75″ and the overall length with the cable head is 21″. The standard pressure port is 1/8″ FNPT but an optional C375CX compression port is available. The standard TEC cable head is 1/4″ but 4mm and 1/8″ are available options.

The APS420 is a dual port piezo resistive permanent downhole gauge. It is similar to the APS400 but has 2 pressure ports.

The APS400 and APS420 are designed to be interfaced to the ASR200 and ASR240 surface readout boxes.
