Series EV Humidity Transmitter

Specifications - Installation and Operating Instructions

Bulletin H-WHT-S

The Compact Series EV Humidity Transmitter is designed to

withstand the elements. A removable sintered filter protects the

polymer capacitance sensor from solid objects that may come in

contact with the transmitter. The transmitter is available with 0 to

10 VDC output signal for humidity.

INSTALLATION

Warning: Disconnect power supply before installation to prevent

electrical shock and equipment damage.

Make sure all connections are in accordance with the job wiring

diagram and in accordance with national and local electrical

codes. Use copper conductors only.

Caution: Use electrostatic discharge precautions (e.g., use of

wrist straps) during installation and wiring to prevent equipment

damage.

Avoid locations where severe shock or vibration, excessive

moisture or corrosive fumes are present.

Do not exceed ratings of this device, permanent damage not

covered by warranty may result.

MOUNTING

The transmitter should be mounted with the sensor pointing

downward to prevent water collection in the housing. The integral

mounting tab has two sets of mounting holes. The larger holes are

for the suspension mounting and the smaller holes are for surface

mounting the transmitter to a wall. Please see figure 1 and 2 for

more information on both mounting methods.

WIRING

Use maximum 18 AWG wire for wiring terminals. Refer to figure 3

and 4 for wiring information.

0-10V Output Models

The 0-10V output models may

be powered with 13-35 VDC.

Note polarity. The maximum

load is 2 mA (5 k ohms). Wire

as shown in Figure 3.

FINAL INSPECTION

0-10 V Output Models:

Verify appropriate supply voltage. The 0-10V output models

require a DC supply of 13 to 35 V for proper operation maximum.

Maximum load is 2 mA.

MAINTENANCE

Upon final installation of the Series EV Humidity Transmitter and

the companion receiver, no routine maintenance is required. A

periodic check of the system calibration is recommended. The

Series EV is not field serviceable and should be returned if repair

is needed (field repair should not be attempted and may void

warranty). Be sure to include a brief description of the problem

plus any relevant application notes. Contact customer service to

receive a return goods authorization number before shipping.
