Applied Measurements Pa600-LR low range pressure sensors come with fast delivery times of 5-7 working days as standard (please contact us if you need faster delivery) and are specifically designed for the measurement of gas and liquid pressure in low range applications.  We can easily accommodate any requirement from a one-off to bulk orders for many thousands of sensors, all within our in-house, UK production facility. Constructed from stainless steel, they are designed to be extremely rugged, yet compact.

As standard the Pa600-LR comes with: Viton O-ring, 303 stainless steel case, 316L stainless steel sensing diaphragm and a G¼ inch male process connection. Alternate case, O-ring material and process connections are available including G¼” female and ¼” NPT male.

The Pa600-LR series provides a wide choice of electrical outputs from its ASIC-based amplifier circuit, these include 4-20mA, 0-5Vdc, 0-10Vdc and mV/V, as well as a ratiometric 0.5-4.5Vdc (10% to 90% of supply voltage) signal that requires a 5Vdc supply (2.7 – 5.5Vdc acceptable range) to suit most dataloggers. The Pa600-LR series can also be supplied with any of our wide range of instrumentation to give you a complete calibrated system.

In addition, we can offer complete customisation to suit your application, please contact our technical sales team. Why not have a look at our full range of pressure sensors plus pressure instrumentation that can be used with the industrial pressure sensor to give you a complete calibrated pressure measurement system.
