AS30 | AS50 Precision Thin-film Pressure Sensors

Pressure Sensors AS30 and AS50

For applications that need consistent high levels of performance, reliability and stability the AS30/AS50 series sputtered thin film units offer unbeatable price performance ratio in a small package size with all stainless steel wetted parts in the volumes required. A wide choice of electrical outputs as well as both electrical and pressure connections means the unit is suitable for most applications without modification. The compact construction makes it ideal for installation where space is at a premium.

The sensors are available in series AS30 with pressure signal and in series AS50 with pressure and temperature signal (dual output).

Features

  • Superior long-term stability
  • High accuracy
  • Rugged design
  • Wetted part in stainless steel
  • Low cost

Applications

  • Hydraulic controls
  • HVAC systems
  • Engine controls (incl. Diesel)
  • Industrial process controls

Notes:

  1. Model AS50 available with voltage outputs 2, 3, 4 and 5 and limited to connections that have 4 pins like electrical codes 1, 2, 4 and 5. Accuracy is 3.5 % of temperature span. Requires additional 2 mA of power.
  2. Ranges 1000 bar and above available with pressure port 07 (M12 x 1.5 HP) only
  3. Range 4 bar not available with 4 .. 20 mA and 0 .. 10 V outputs.



To create a code for a customized version, we will use the code for the nearest standard version and add a -Zxxx number that defines exactly the specs of the customized version!

For sensors with individual calibration certificate, a "K" has to be added to the sensor code. (additional charge!)

Please order all mating connectors and cables separately!

The specifications are subject to change without prior notice.

Information in the PDF datasheet (see above) may be more detailed. Due to continual product development, ALTHEN and partners reserve the right to vary the foregoing details without prior notice.
