HT/HWS SERIES

Wall Mount Humidity Transmier Thermostat Humidistat Functions

VERIS INDUSTRIES

Independent RH, Temp, and Analog Setpoint Outputs

DESCRIPTION

All HT/HWS Series institutional grade relative humidity/temperature transmitters are designed to meet the rigorous needs of pharmaceutical labs, hospitals, science labs, and other settings that call for precise environmental control. Internal jumpers control access to a feature that allows adjustment of the calibration osets. The devices can also be made tamper resistant using a jumper to disable keypad programing functions. HT/HWS models are calibrated with NIST traceable calibration equipment.

Analog Output Transmitter

Analog output models feature a keypad to make adjusting humidity and temperature setpoint values easy. They transmit the setpoint values back to a control system by means of dual outputs. A slide-switch allows easy selection of output type, either 4-20mA or 0-5V/0-10VDC signals. Dual outputs enable eortless control of both humidity and temperature in a single, compact sensor.

Setpoint Relay Transmitter

setpoint devices

The HT Series setpoint relay models also oer thermostat or humidistat functionality. Two separate relays can be congured to control heating and cooling when in thermostat mode, or humidifying and de-humidifying when in humidistat mode.

HWS models oer the same precise humidity measurement and control as the HT, but without the temperature and thermostat features.

APPLICATIONS

● Hospitals and operating rooms, pharmaceutical labs

● Clean rooms

● Food processing plants

● Environmental testing facilities, and other institutional applications

FEATURES

● Independent RH and T (HT relay) or analog setpoint outputs (HT analog)

provide application exibility

● LCD for local display of readings and setup values

● Oset function adjusts calibration inter vals for both RH and T (HT models)

● Switch-selectable 4-20mA or 0-10V/0-5VDC analog outputs

● Multi-point calibration to 1% RH, traceable to NIST

● Replaceable RH sensor element supports eld calibration oset...saves time

● Semiconductor temperature sensor can be eld calibrated

† The HS sensing element has a 1-year warranty. The element is not a part of the 5-year product warranty. * Specied accuracy with 24VDC supplied power with rising humidity **Reset Rate is time required to recover to 50% RH after exposure to 90% RH for 24 hours One side of transformer secondary is connected to signal common, so an isolation transformer or dedicated power supply may be required. RTD/Thermistors in wall packages are not compensated for internal heating of product.
