Temperature, Humidity, Pressure Monitoring for Lab Rooms

Good Day,

Looking for a suitable (economical/viable) solution against the attached requirement.
In the whole system I have:

1. 02 Fresh Air Handling Units and I have selected 02 "RP-C-12B-F-24V"

2. Chiller Plant, the selected controller is "AS-B-36".

For this Lab Room requirement what can be the solution! i initially selected Smart X Sensor "SXWSBTHXXSXX+SXWSCDXSELXX" and EPU-305-LCD and selected 03 "RP-C-12B-F-24V" as 04 Smart X Sensors can connect to 01 RP-C-12 and pressure sensor will utilize the UIs of RP-C.

Is this a safe selection and can we proceed with this or can we have another smart selection!

Please share your comments.
Br.

HI,

Selection looks good.

Pressure sensor is bi-directional so, can read -/+ as if this is reading lab pressure, then the pressure would be -ve, however if it were to go +ve you would still want to know.

Where's the pressure sensor mounted? Use to put one tube in a dummy sensor housing in the space being monitored on my projects, the other of to the reference point.

Hello

regarding the use of the EPU-305-LCD.
Depending on the lab environment this unit may not be suitable.
See attached specification sheet and the note

Note: This product is not intended for life or safety
applications. Do not install this product in hazardous or
classified applications.

Zero drift for this product is 2.5% typ, which will not be acceptable in Healthcare over pressure rooms.
We do not have an alternative as of today that fits this application. You can check out products from Setra. They will fit the bill here
