Current type temperature and humidity transmitter BM-RHT-6AS

Product Details

Overview

The BM-RHT-6AS temperature and humidity transmitter is a low operating voltage current output transmitter with a nominal operating voltage of 24V. It is a sensor with two channels (4~20) mA output for temperature and humidity. Made with high-precision calibration free digital output temperature and humidity sensors and low-power microcontrollers, it has short response time, high accuracy, and good stability.

1. Low operating voltage, analog current output

BM-RHT-6AS has a nominal operating voltage of 24VDC and (4~20) mA output, suitable for providing 24V DC field equipment

2. High precision, high stability, high reliability

The BM-RHT-6AS series adopts high-precision calibration free digital temperature and humidity sensors, which have high accuracy, short response time, high stability, and high reliability

3. High load capacity

The BM-RHT-6AS series temperature and humidity transmitter can drive a maximum load resistance of 450 Ω at a working voltage of 24V

4. Low self heating effect

The BM-RHT-6AS series features low operating voltage and thermal isolation design, greatly reducing the impact of transmitter self heating on measurement accuracy.

5. Reverse power protection

The BM-RHT-6AS series temperature and humidity transmitter has a reverse power protection function to prevent equipment damage caused by reverse power polarity.

6. Surge and ESD protection

The BM-RHT-6AS series temperature and humidity transmitter provides 500A surge protection and contact discharge 6kV air discharge 8kV ESD protection, making the product suitable for harsh electromagnetic environments.

7. Application scope:
Computer room, data center, telecommunications cabinet, HVAC, greenhouse, weather station, automation, warehouse, incubation room.

Instructions:

(1) The maximum load resistance is calculated according to the formula RL ≤ (Vs-15)/0.02, where Vs is the operating voltage in V and RL is in Ω

(2) The self heating effect is the difference between the temperature value measured within 1 minute of power on and the temperature value measured after 30 minutes of power on. The self heating effect has been corrected for a working voltage of 24V, a load resistance of 250 ohms, an ambient temperature of 25, and a relative humidity of 75%.

(3) Response time refers to the time it takes to apply a step to reach 63% of the step value.
