Stability Chamber

A portable calibration chamber is an essential tool for calibrating various types of sensors in the field or at remote locations where access to standard laboratory facilities might be limited. This device is designed to provide a controlled environment to simulate specific conditions (such as temperature, humidity, pressure, or gas concentrations) in order to ensure the accurate and reliable performance of sensors.

A walk-in stability chamber PLC specification typically includes details like: temperature and humidity range (e.g., 20C to 60C, 40% to 95% RH), accuracy (± 0.2C, ± 2% RH), uniformity (± 2C, ± 3% RH), data logging capabilities, alarm functions, multiple sensor points for mapping, user interface (touchscreen HMI), communication protocols (e.g., Modbus), and compliance with relevant standards like ICH guidelines; all controlled by a programmable logic controller (PLC) system for precise environmental control within the chamber. The Display or HMI (Human Machine Interface) is a 7 Colour Touch Screen display. It shows values of temperature/ Humidity with Some other important features: — PLC IP Address setting — Component Working Hours — Password protection for set values & calibration mode — User Manual, Troubleshooting & Preventive Maintenance procedure — Display of Alarms & Its history — Controls access to door opening. User needs to give password to unlock The door from outside. Control access can be provided to up to 25 users. Their activity for door access is also tracked. Audio and visual alarms are generated for — Temperature deviation (High & Low) — Humidity deviation (High & Low) — Door Opening — Utility failure ï† Mains failure ï† System unhealthy Error. The controlling system is fully PLC based system. It consists of PLC controller, HMI, Relays, Contactors, Overload trip devices, Surge Arresters, Mains MCB etc. The control panel has IP22 protection 1. PLC(Programmable Logic Controller) — Complete operations driven through PLC with data storage capacity of up to 5000 readings on the PLC itself (no additional hardware required) — Records temperature /Humidity readings of all connected sensors — Operates the safety devices — Ethernet communication port for PC communication — Completely modular system — Standard hardware available globally — Generates alarms upon utility failures, fault and deviation in control parameters — Alarm trans mission to multiple locations 2. Surge Arresters — Removes second and third harmonics form supply line. — Increases the life of control panel components and electrical components connected to control panel. — Protects electrical components of chamber form in coming surges and Harmonics.

Stability chambers are used to test products under controlled conditions. They have a range of specifications, including temperature and humidity ranges, construction, and air circulation. Construction Made of stainless steel and Insulated with high-density PUF Uses a motorized blower to maintain uniform temperature and humidity Uses CFC-free compressors that are hermetically sealed Heating Uses SS tubular air heaters. Uses a stainless steel tank and immersion heater with automatic water filling. Control system Uses self-programmed PID / PLC controllers.
