PCS-DRP70 Electronic Pressure Controller

Solid design for reference pressure control ≤ 70 bar

The PCS-DRP70 is a digital dual valve pressure controller configured and manufactured for PCS by Specken Drumag, containing some unique features. This unique product of Swiss/German quality starts at a vacuum and ranges up to 70 bar gauge. We often recommend this unit to set the reference pressure on Equilibar dome-loaded back pressure regulators.

Exclusively for PCS customers, these instruments have been optimized to control pressure in a small dead volume. Another unique feature is the option to use an external sensor. This allows closed-loop control, and it also facilitates the use of more sophisticated pressure sensors.

Strong pair with Equilibar Research Series

The combination of this electronic pressure controller with the Equilibar Research Series control valves has demonstrated to be very successful in many R&D applications from vacuum up to 1000 psi, matching the pressure limits of the popular LF-, and HF-series Equilibar BPR’s.

Plug & Play Functionality

This PCS-DRP70 digital electronic valve controller can be supplied with an optional USB cable and software for computer connection. With the software, you can plot the actual sensor and valve values and tweak the PID settings.

Fail-Safe Settings

This type of dual valve controller provides 3 options for fail-safe settings:

“Pressure maintain” – both valves close on failure and the pressure is maintained
“Pressure release” – the outlet valve will open on failure and the pressure is released; reference pressure will be released quickly and the Equilibar® valve will open to release the pressure
“Full pressure” – the inlet valve opens on failure; reference pressure will build up quickly and the Equilibar® valve closes

Product Features – all benefits of the PCS-DRP70

This electronic pressure controller is a high-quality product with many beneficial features:

Available from 100 mbar abs up to 70 bar gauge
Range adjustable – for example, a 0…70 bar g controller can be re-ranged to 0…35 bar gauge
No bleed – minimal risk of contamination
Larger orifices than some other electronic pressure controllers and thus less risk of clogging
USB interface for monitoring and configuration
Software selectable analog signals – 0…10 Vdc | 4…10 mA | 0…20 mA
Remote sensor for closed-loop optionally available
European BSPP thread for use with a standard adapter with bounded o-ring
M12x1 electrical connection (standard 5-meter cables available from our stock)
IP65 protection class
Fast delivery from a reliable and responsive European manufacturer
All versions are CE compliant
Affordable and cost-effective in most situations!
