Product Overview

The  is a wall-mounted Temperature, dew point, and differential pressure display screen with three rows of 3-inch high-brightness red LED digits:

• Temperature (°C) — range −20 to 100 °C

• Dew point temperature (°C)

• Differential pressure (Pa) — negative values supported, one-decimal resolution

Labels can be produced in English, Chinese or bilingual layout, with or without custom branding, so the panel reads clearly to every operator on the floor.

Key Specifications

Key Functions

1. Three Parameters, One Glance

Instead of walking the room with a thermometer and a manometer, staff see temperature, dew point and differential pressure simultaneously on one high-brightness panel. The 3-inch red digits are legible from meters away, even under cleanroom lighting.

2. Sound and Light Over-Limit Alarm

When any actual value falls below the lower limit or exceeds the upper limit, the panel triggers an audible and visual alert: the buzzer sounds intermittently, the top beacon flashes and the out-of-range value flashes on screen. If values stay within limits, the display stays quiet — so any alarm means "act now." Reminders can be cancelled via the remote control or host software without clearing the flashing data prompt.

3. Error Value Correction (±20.0)

Field calibration is built in: each value can be corrected within a ±20.0 range via remote controller or host software, so readings always match your reference instrument — no need to return the unit to the factory.

4. Remote Controller and Host Software Configuration

All settings — limits, correction values, reminder behavior — are set via the included 25-key remote control or through the host software. No ladder-and-laptop reprogramming every time a setpoint changes.

5. 7-Day Power-Off Data Storage

Even after a power interruption, stored settings and data are retained for up to 7 days, so the display returns to normal operation without reconfiguration.

6. TCP/IP and RS485 Communication

The board connects through the top aviation plug and network port wiring, supporting TCP/IP and RS485 protocols — the standard interfaces for BMS, SCADA and any Environment Monitoring System Panel.

System Architecture: From One Board to a Plant-Wide Network

A single display solves one room. SUNPN's architecture scales to the whole plant:

Environmental Data Boards → 200C Gateways → Local Area Network → Database Server / Software Client / LCD Terminal

The self-contained software system performs real-time monitoring and data collection of every device, with:

• A real-time monitoring dashboard for all boards across factory areas (temperature, humidity and alarm status at a glance)

• Abnormality data logs with timestamps — every out-of-range event recorded as it happens

• The OkMes background system for real-time monitoring and timely feedback: alarm records, device data records, historical records, exception frequency analysis and exportable reports

This means the display is not just a local signboard — it is a data node in your quality system, producing the records auditors and customers ask for.

Typical Applications

How to Choose a Cleanroom Environmental Monitoring Display

Before you buy, check this list:

1. Parameters — confirm temperature, dew point and differential pressure are shown together, and whether CO₂ or PM2.5 can be added later.
2. Visibility — 3-inch or larger digits for reading across the room.
3. Alarms — user-defined limits plus sounder and beacon output.
4. Calibration — on-site error correction (e.g. ±20.0) without factory return.
5. Communication — TCP/IP and RS485 for integration with your Environment Monitoring System Panel.
6. Customization and support — a manufacturer that supports OEM/ODM and long-term project supply.

Frequently Asked Questions

Q1: What parameters does the display screen show?
Temperature (−20 to 100 °C), dew point temperature (°C) and differential pressure (Pa, one decimal, negative values supported) — all three simultaneously in 3-inch red LED digits.
 

Q2: How does the alarm work?
When a value exceeds your set upper/lower limits, the buzzer sounds intermittently, the top beacon light flashes and the out-of-range value flashes on the panel. The reminder can be cancelled by remote control or host software.
 

Q3: Can the readings be calibrated on site?
Yes. Each parameter supports an error correction range of ±20.0, set via remote controller or host software.
 

Q4: How does it connect to our Environment Monitoring System Panel?
Through TCP/IP and RS485 with network port wiring and a top aviation plug. Multiple boards can be networked via 200C gateways into the OkMes monitoring software for dashboards, alarm records and historical reports.
 

Q5: What happens after a power failure?
Settings and data are retained for up to 7 days, and the display resumes normal operation once power is restored.
 

Q6: Can the panel be customized?
Yes. Display content, label language (English/Chinese/bilingual), panel layout and branding can all be customized. Contact SUNPN with your requirements.
