LPI-pH

Standard Unit: 0~14pH In, 4~20mA Out, with LCD.

Description:

The LPI-pH is a loop powered, isolated, pH Cell input, to 4~20mA output transmitter, with integral Pt100 RTD temperature compensation, and LCD display of 0~14.00pH.

The LPI-pH is the device to choose when a pH probe is installed in a corrosive, damp, high earth current or electrically noisy environment. The IP67 rating of the transmitter enclosure, together with the corrosion proofed circuit board, give the LPI-pH high immunity to damp and corrosion, allowing it to be mounted close to the pH probe. Having the transmitter close to the pH probe means that the highly sensitive pH probe output signal is amplified and turned into a robust 4~20mA signal before noise exposure from long cable runs can effect it.
The unit also features internally accessible, finger adjustable, 15 turn slope and offset adjustments, for easy calibration of the pH sensor, in conjunction with the LCD Display.

The 4~20mA output from the LPI-pH can be run for long distances to better environments where standard process controllers can be used safely. The LPI-pH fills a niche where it has often been necessary to install low IP rated, dedicated pH instruments in an aggressive environment.

2100-A4-HWD

Features:

Independent Temperature and Relative Humidity Outputs.
%RH Accurate to 1.0%.
Temperature Accurate to 0.1%.
Low Cost.
Easy to Install.

Ordering Information:

The Standard Calibration for the 2100-A4-HWD is:
(i) DIN Pt100 inputs, both Calibrated for 0~100C temperature range;
(ii) 4~20mA outputs for both relative humidity and temperature.

Notes:

1. This unit replaces the IN-HWD and uses the IN-HWD software in conjunction with the 2100-A4 software.

2. In addition to the standard IN-HWD features all the other features and options of the 2100-A4 can be used except the 2100-A4-HWD does not have PLC Retransmission Software.

3. Analogue input 1 and analogue input 2 are available as Pt100, mV, V, mA and are all ranged 0/100C irrespective of the input type.

4. The standard analogue outputs are available.

5. The input signal can be calibrated using the zero offset software available in the Intech Micro 2100 series configuration software.

6. The Scada can read back %RH as the value of AO1 and Dry Bulb Temperature as the value of AO2.

7. The 2100-A4-HWD can run fully independent of a Data Hi-Way as a stand alone transmitter and or also on the Data Hi-Way.

8. In certain parts of the %RH curve a small change in temperature can cause a large change in Humidity and so the Software in the 2100-A4-HWD has the same damping function as the IN-HWD to ensure stable readings. In addition to this the standard 2100-A4 input averaging software is available.

LPN-H-F	100mm Flange for LPN-H-D

Note: 0~200F temperature output optional. Please specify when ordering.

Description:

The LPN-H is a complete relative humidity and temperature sensing module, with two loop powered 4~20mA output signals, representing 0~100%RH and 0~100ºC (0~200ºF).

Two versions are available:
(i) Wall mount.
(ii) Duct mount.

Both versions come complete in an industry standard aluminium connection head. The relative humidity sensor and temperature compensating sensor protrude from the head inside a protective cap. This cap allows air to circulate to the sensors.

Reliability:

The wide range of the humidity and temperature sensors offer long term reliability over a broad range of applications. The sensors resist contaminating vapours such as organic solvents, chlorine, and ammonia.
