2% RH TRANSMITTER W/20-40mA

Dwyer Instruments RHP-2O1B 2% RH TRANSMITTER W/20-40mA The most versatile of the audible transmitters, this transmitter is designed to transmit a signal to an external meter or process control system. By connecting an external meter or control system to the transmitter, large process areas that are not within range of an audible transmitter can be monitored. These units are designed for use in environments where ambient noise is a problem. The 20-40 mA output may be used to drive a digital display indicator (such as a Magnehelic®) or the signal may be sent via 4-20 mA loop to a process control system such as Life Safety Systems

The RHP-2O1B is a rugged, waterproof, precision 2% relative humidity transmitter. The RH output signal is an analog 20-40 mA current loop signal with a 0 to 4 volt square wave output.

The RHP-2O1B 2% RH transmitter lets you send humidity data over the air. This feature is useful for constructing a "wireless weather station" that is linked to an Analog Input Module (AIM) and display, such as the RS-232 Serial Interface module. Because the measured humidity is transmitted directly to the display, you can use an external probe with a 4 to 20 mA transmitter attached to monitor relative humidity.

The RHP-2O1B 2% RH transmitter is your solution for fast, accurate, and reliable relative humidity measurements.

Allow your microprocessor-based transmitter to display relative humidity, period! The RHP-2O1B 2%RH transmitter will connect directly to your existing 1-wire network and provides an output signal to a compatible controller, such as our PSI-4iC 4 Zone Controller.

The RHP-2O1b is a transmitter that utilizes an important wet-bulb temperature measurement technique to calculate relative humidity from 20-40mA output.

The RHP-2101 and RHP-2102 are precision electronic humidity transmitters with a 2% total-hydrogen leak rate. All connectors, sensors and wiring harnesses are provided in the package. There is no user calibration or setup needed. The unit has a built-in temperature compensation circuit and is designed for harsh environments.

The DR2/10/20 instrument combines a Digital Thermometer and a RH Transmitter in one compact unit. The DR2/10/20 mounts directly to the thermostat without use of an external sensor probe. Unlike ordinary thermometers, the DR2/10/20 includes an integral RH transmitter and is factory calibrated at 1%RH with a range of 0-100%RH continuously. Both the temperature and relative humidity are displayed on the backlit LCD display. The thermometer portion of this unit is ideal for domestic heating and cooling applications, while the transmitter may be used with temperature controlled process equipment such as incubators, chillers, and refrigeration systems.

This family of current-output transmitters converts a process variable to a low voltage DC signal. They provide a linear, stable output for interfacing automated measurements. Low level signals are available in either 0-20 or 20-40 mA versions.

The RHP-200 provides a 2-wire transmitter with standard NMEA 2000® output suitable for use with any NMEA 2000® device. Also, it contains a single relay output that can provide switching between NMEA 2000® devices.

The RHP-20 (RH) is 1½"H x 1½"W x ¾"D, 0.3 lb and includes a built-in calibration screwdriver and key. The unit is hermetically sealed in a cast aluminum case that protects the unit from contamination of the process or surrounding environment.

Durable and reliable, a great choice for HVAC/R field service applications where reliability is the deciding factor
